Nanofrog, I have a tremendous amount of respect for the sheer breadth of knowledge you drop here on a regular basis, and I can't find fault with anything you're saying.
But...
I'll bet you $100 that 2010 = The End of Heavy Metal in its' current form. What gets released as the next "Mac Pro" will absolutely not be the current form factor. It has had one of the longest runs in design history, but looking into my crystal ball, it's
over.


I'm with
Schismz on this. A) Thank you Nanofrog. B) I think Apple is going to roll out a newly designed Mac Pro, or replace the Mac Pro with something different, that bases it's form factor on ThunderBolt.
This new form factor won't make any economic sense, strictly speaking - at least at first. However, Apple will use it to showcase what people
can do with TB and desktop computers. It will debut new ideas of how a desktop computer should work. I wish I could tell you what they are, but if I could then I'd be working at Apple - in which case I still couldn't tell you

--
Apple now designs the laptops that set the benchmarks for that segment, imho. Often the other companies exceed that benchmark as well - but they still are now needing to think about what Apple is bringing out next.
Apple doesn't own the desktop segment like they do laptops. I think they would like to - because why wouldn't they? Just because they haven't really competed in the desktop segment doesn't mean that they are not interested... it just means they were interested in something else for a bit.
Thunderbolt doesn't really make a lot of sense for laptops. Most laptops are used by ordinary folk, who don't do a lot of connecting to peripherals. They type on the keyboard, they send email and pictures. They research student essays. With iCloud, they data can be backed up by Time Machine without needing an external disk. For professionals who need fast connections, why not just ExpressCard slot on the Pro laptops. Lot easier than devising a whole new protocol. I believe TB makes more sense for desktop computers, where more people tend to attach more things.
I think the TB was introduced on the laptops to get people used to the idea. I think the next Mac Pro is going to get people
excited about TB. It will get all sorts of press coverage. It will vault Apple to the top of the mainstream press, again, as their reporters drool over something new and cool. So what if Apple looses money on the new Mac Pro? With the numbers that they sell, even if they lost $1000 per unit - it's not going to be a great deal of money. And the press coverage will sell more units of their profitable line.
Think about the 1st generation Mac Book Air. It was a dog of a computer. It was slow, everyone complained about the lack of ports. It was expensive. The battery was non-user-replaceable. It didn't have an optical drive. I bet the 1st generation of Air lost money for Apple. But it was the vehicle for rolling out a bunch of new ideas, of getting a whack of press coverage, and it became - in time - hugely successful once people got used to it.
I think the next Mac Pro is going to be the same, and that it's going to use TB in very interesting ways.
And finally.... Apple may have delayed introducing the new Mac Pro with TB because they knew that Steve Jobs was declining. If Tim Cook introduces something really exciting with TB, despite the fact that all of the hard-work was done pre-changeover, he will get the credit - and it will cement in people's minds that just because Steve is gone, Apple has not lost their innovative spirit.
I've gone on far too long, I'm sure, about something I know far too little about.
I'll just conclude with this. For engineering reasons, there are reasons to keep the Mac Pro going, waiting for the next chip, etc etc..... But sometimes Apple just does things for the splash effect, for marketing. I think this will be one of those.
