The current Mac Pro has six TB2 ports so it can drive three 5K displays if your willing to dedicate all six ports.

This assumes a 5K Apple Display would even have Thunderbolt 2 inputs...or that there would be some kind of dual-Thunderbolt 2 to Thunderbolt 3/USB-C adapter. All big assumptions at this point, not to mention the graphics impact that would have on the machine.

The cleanest external 5K implementation would be a Thunderbolt 3 spec that support DisplayPort 1.3 instead of the current 1.2 standard. Problem is Intel has no plans to support DisplayPort 1.3 until Cannonlake at the earliest so we're still a year or so out from 5K being a resolution that can be pushed comfortably without some kind of Frankensteinian solution either through MST (multi-stream transport) or some kind of eGPU setup.

If they give us the option with dual cable. I could give up 4 ports, the remaining two would be enough for my raids.

Haha Frankenstein solution :D

- Although it would still be a sort of MST solution, Thunderbolt 3 is able to support one 5K display at 60 Hz over one cable. Should be pretty clean.

No I was saying Thunderbolt 3 with DisplayPort 1.3 (which exists nowhere yet). That would be able to do 5K over a single cable using SST instead of MST.

- Yes, I know. I was just saying that the current way with Thunderbolt 3 and two DisplayPort 1.2 streams over a single cable is also fairly clean. Not as clean, but pretty good.
Good enough for me, but considering Apple probably don't want to update the display for > 3 years they might want to wait for DisplayPort 1.3.

Does anyone know if it is possible to connect a Thunderbolt 3 only display to an ATV 4? I would love to use my Apple Display as a small TV when not plugged into my Mac.

So looks like with the new 4K and 5K LG displays the rumor about a new Apple Cinema Display - much less one with a built-in GPU - are either debunked or it's going to be designed not just for new TB3 Macs, but also older TB2 macs (so I am guessing a "hydra-head" cable end with one USB-C/TB3 connector and two Mini-DisplayPort/TB2 connectors).

New Apple Display isn't happening. Clearly, Apple decided to exit the display market, and partner with 3rd-party makers instead.

The upcoming 5K LG looks pretty decent and also reasonably priced - I will likely be getting one.

"In the case of the 4K model it can be driven using a single DisplayPort 1.2 stream over a normal USB-C port. The 5K monitor requires two DisplayPort 1.2 streams and so it is a tiled display."
- Doesn't say it can be used by anything else than Thunderbolt 3 machines. Apple's website also mentions a Thunderbolt 3 machine as a requirement.

At the very least, since it has only one signal input in the form of a Thunderbolt 3 port, you would need some way to turn two cables into one in order to connect to non-TB 3 machines.

(Streams ≠ cables.)

"Based on the fact that Apple said they worked with LG on their new monitors to develop them (in the keynote), I think Apple displays are RIP."

I called this two years ago.
But some folks "just had to keep believin'".

Having said that, I also predicted a few days ago that if Apple had released a 5k display, it would sell for around $1,500.
The LG 5k display sells for $1,300 -- not that far from my predicted price point.

How many folks are willing to pony up that much, in addition to the already-overpriced MacBook Pro's …??

Predicted huh, psychic or something? Or just looking for validation that you made an assumption that seemed logical to you?
