Tested this out also. Went to the apple web site for the harry potter and 1/2 blood prince and downloaded the 1080p trailer. Imported to itunes and it ran just fine.

Man, that's fantastic news. Now, can you open the movie info and post the numbers there? The real question is to see what quality of 1080p it can handle (which can come from info like data rate, etc) Open the trailer in Quicktime, then choose the "Window" menu, and "Show Movie Inspector".
And, the other "biggie" is can you hit "info" or similar on your HDTV so that it shows if it is receiving a 1920x1080 signal vs. a 1280x720 signal while those are playing the trailer. One guy thinks that even if the
TV can decode a 1080p file (which is the hard part by far, and you seem to be putting that one to bed), the TV may still be outputting that video as 1280x720, effectively decoding a 1920x1080 then dynamically down-converting it to 1280x720 before it pushes it out to your HDTV. That wouldn't make a lot of sense to me (the decoding is really the workload here), but you might be able to definitively address that one.
Pretty please?

I have a Panasonic TC-P58V10 (58" 1080p plasma) and when I play one of the HP trailers it tells me via info that it's in 720p. So it looks like it is only passing it off as 720p even though it is able to handle it.
Hmm, that's a bit disappointing (but thanks). Have you been through all of the possible settings menus on the Apple TV to see if there's anything that lets you change the screen resolution?
The old AppleTV up-scaled to 1080P (selectable via options) so this version shouldn't be any different.

All right. We're cooking now. Could you try the other one and post those numbers.
The most ideal trailer would be 1920 x 1080, that fills the screen with no letterboxing, has a lot of fast action/camera moving (so that everything in the picture is moving), and that is also in 5.1 surround sound. I'll jump on Apple site and see if I can find one like that, but if someone beats me to it, please post it.

I'm hoping that's true; but, you know, the old Apple TV had 40GB/160GB storage, and the new version is pretty different in that regard

There's belief that since this one doesn't have component jacks, it auto-senses it's way to this setting via HDMI.
That's disappointing that the first trailer is showing a pass as 720p. It would be just about terrible if Apple built in hardware strong enough to decode 1080p, but then pushed the frames only at 720. The decoding is the hard part.
Please try a few more tests. Can you find any one that shows as 1080p video via your HDTV "info"?
Great news!
I would be amazed if someone can hack it and allow 1080p output. Sweet!
Now my second wish is external drive support, so endless storage and no need for my Mac to be on.

The other thing that would suck if there were no display settings is that that was how it was possible to choose between 25/50Hz and 30/60Hz refresh rates -- quite important for people with international collections.
(No 1080p also means no 24fps which would also be pretty handy, though perhaps not within the realm of reasonable expectations at this stage.)

It is different. There's no setting for output anywhere under settings. Not under General or Audio & Video.
I played the same trailers via Plex on my Mac Mini and my TV reads 1080p.
However, I also did my best to distinguish detail/quality differences between the two playbacks (Plex on Mac Mini vs ATV2) and the same level of detail seemed to be there in items like Dumbledore's beard, etc.
I'm happy to test more trailers or whatever. I'm converting a piece of Avatar right now into a playable format.

Again, I think the resolution selection options of the old ones was because it had analog (component) connections. HDMI can sense the display settings.
Right now, it's looking like theTV has some hardware capable of decoding 1080p files (which is the biggest task), but it may have either a hardware or software limiting function pushing only 720p frames out of the box to the HDTV. I'd love for anyone to post that I'm wrong (that they are getting 1080p video signal received at their HDTV, shown by clicking something like "info" so that it shows 1920 x 1080, not 1280 x 720).
Please, anyone!

Thank you for executing tests, and posting results. I look forward to the Avatar test results. If you're using Handbrake, it would be especially helpful if you really push the settings.
You guys are missing an important part.
The processor may be capable, but maybe the graphics hardware doesn't actually have 1080p output; after all, it requires a higher signalling rate than sending a 720p signal over HDMI. I would assume, since it is using iPad and iPod touch hardware, they did not update the capabilities.
Decoding != the I/O interface capabilities of a device. If you have extra CPU power, you can decode all you want. It doesn't mean you can push it to the outside world if your I/O interface is lacking.
The new Apple TV doesn’t do that. The old one supported 480p, 720p, 1080i and 1080p outputs. The new one only supports a 720p output. Sounds like an iOS limitation. Most iOS devices only support 480p and 576p output via the Apple component cables. The new Apple TV is the first one to support 720p. Before the Apple TV, the iPad supported the highest output resolution at 1024x768 using the VGA to Dock connector.

That's what we're trying to figure out. Yes, you are right, but I hope the implications of what you are suggesting are not right in this case. I'd really love to see someone post that they can get any 1080p signal from the
TV to their HDTV (as shown by an "info" or similar click on their HDTV remote during playback).

Anyone with the knowledge able to look at the ifixit breakdown to determine if this would be a hardware limitation (thus not able to be fixed with a future incarnation of iOS) or a software limitation (the hardware is there, iOS just needs an update to use it)?
This is beginning to sound like trying to figure out how to play 5.1 when the first ATV came out.
Again, the best news is that the new Apple TV isn't bitrate limited nearly as much as the old one which makes the difference in quality between a 720p rip you can play on your Apple TV and a Blu Ray disc even smaller than it already was. If you care about quality, then that's what you'll care about most.
The other good news is if you have a 1080p file, it will still play on your Apple TV. Everything else is just minor details in my opinion.
Here's something I bet most people don't know... Apple gets its source material from a much higher quality source than Blu Ray which is why their 720p iTunes content looks so good.

The new Apple TV has a fixed output resolution of 1280x720 (720p). It can't output at 1080i/p even if it could decode at that higher resolution. The same is true on the iPad, it can decode 1080p content but there is no way to get that level of resolution out of the "box."
Case in point, I posted information on the iPad's ability to decode 1080p content several months ago so there is nothing new here.

There's one other Apple chip on the board ... no idea what it does. The A4 is doing the rest. Need to trace the HDMI connector back to whatever chip it's connected to ... but most likely it's going straight to the A4. I don't think the max specs of the a4 are known when it comes to display output. The highest anyone has seen previously is the iPad.
