...as opposed to them taking the picture for completely no reason?
What picture? It is a bunch of photoshopped stuff. Are you refering to
If so please note the Mac Pro is
not connected to the display. How's that for significance in through pictures?
A "pro" monitor, following in the legacy of the ACD 30" , would be a 30 bit color , 100+% gamut monitor like what the "pro" NEC , Ezio , etc. monitors are like. What Apple is doing is adding "more stuff" to a monitor that will probably go for $700-800 in the next year and tying to Apple only set-ups.
Apple could strong arm some video card vendor into doing a GPU + TB card but that just putting a round peg into a square hole. Typically Apple doesn't do that.
I'm pretty sure it is. The display signal on a Thunderbolt cable isn't even done under the Thunderbolt protocol. It's just a bog standard Displayport protocol. Nothing special. Even for dual mode devices.
Not by the can't be.
Thunderbolt.

"... Bitrate 1.62, 2.7, or 5.4 Gbit/s data rate per lane; ... "

Note that DP gets
max 5.4Gps per lane (graphic in right column). Intel was quoted as both the PCI-e and DP traffic travelling on separate lanes at 10Gps. Guess what? that isn't DP. It also makes sense if shipping the data for two large screens down one lane you'd need something faster than DP's top speed. Also the topology of the network is going to be "know" to TB so it should be shuttling the data from source to destination.
Physically they are using a socket with the same 4 lanes. The protocol on those two lanes is different that DP or PCI-e .
It is quite another thing when a non-TB cable plugs up and starts using legacy DP singals. That that point the TB control can switch to legacy mode and pass along DP over the 4 lanes and audio over the aux if they are all hooked up to the controller.
