Like I said, they shot themselves in the foot with Thunderbolt.
Thuderbolt isn't the blocking issue here.
They publicly committed to it in a big way, and now there aren't any LGA2011 boards with native ThB support
Last year there were no LGA1155 motherboards with Thunderbolt either from anyone until Apple introduced several.
It isn't that hard. You hook the discrete Thunderbolt controller to x4 PCI-e lanes ( of which an E5 Xeon has plenty) and to a display port ouput which a wide variety of discrete GPUs and your are done.
It is almost ridiculously easier to do with it is a 1155 motherboard because the CPU/GPU output comes out of the same support chips as the x4 PCI_e lanes you are also likely using. For example one of Intel's board
[overview on a couple here

Both outputs coming from one support chip just makes it easier. It isn't necessary. It is actually a little odd that Intel runs the video output to the I/O Hub in the first place. The GPU is in the CPU package. With a different pin outs and modest increase in internal circuits the signal could just as well come out of the CPU package. In the next iteration, Haswell, it probably will ( along with x4 PCI-e lanes to hook the TB controller to. ).
The iMac has a discrete GPU hooked to its Thunderbolt controller. It isn't rocket science. It was done last year.
There is nothing about socket 2011's PCI-e lanes or discrete GPUs that make it any harder if just willing to wire up a solution. It takes more motherboard space to do it without a iGPU but the Mac Pro isn't that pressed for motherboard space. There are plenty of competing workstations out there with more PCI/PCI-e slots , more discrete SATA controllers , motherboard SATA headers , etc. that clearly demonstrate it is well within technical possibility to put a bit more on a motherboard than the current Mac Pro does.
and they look really stupid.
They looked like they screwed up. Everyone makes mistakes from time to time. This is a big FUBAR one though.
Their flagship model is the only machine that does not sport this
It isn't there flagship model. You are smoking something pretty strong if you think the Mac Pro has been their flagship model anytime over the last 5-6 years.
But it would be even worse if they released a brand-spanking new MacPro WITHOUT ThB!
That is ridiculous statement. If Apple introduced brand new Xeon E5 with all the possible features and bleeding edge new GPU video cards from the mainstream market and the
only feature missing was Thunderbolt, then overwhelming response would have been positive.
The majority of Thunderbolt kool-aid drinkers that would have been disappointed, but they aren't a major fraction of the Mac Pro market.
And there would a very small subset of folks who have highly mobile jobs with some very expensive Thunderbolt devices with
no PCI-e equivalents ( that is an extremely small number of devices of a relatively extremely small pool of Thunderbolt devices ).
I bet they're mighty pissed about it, too. They have to wait until Intel remembers to include ThB in their Xeon lineup.
If you are implying that Apple has to wait until Intel builds a reference board with discrete controllers and flush out the majority of the design details before Apple can copy off their "homework" ... I can't image they would be pissed. Can't really be pissed if just perpetrating you have a skill set that you don't. Perhaps they could be pissed that they didn't hire any compentent designers but that's about it. Putting Thunderbolt on a board isn't rocket science.
The vast majority of vendors aren't doing it primarily only because the controllers are expensive and the technology isn't broadly rolled-out.
"... Right now, the necessary Thunderbolt controller chip from Intel costs more than quadruple that of the equivalent component for an earlier high-speed connection technology, FireWire. ..."

Most board and system vendors are squeezed for margins don't want the margin hit. 4x FW controller cost is trivial for the Mac Pro to handle. The only bump in cost if would be if Apple started shipping with two GPUs on board (one PCI-e card and an embedded one to supply Thunderbolt with Display Port signal or higher priced PCI-e card because some custom kludge to get the DisplayPort off the card. ).
Whahaha, that's what you get for being an Intel preferred development partner!
So there is another vendor whose workstation's CPUs top Intel's ? Apple not being able to do their own "homework" wasn't Intel's problem.
The delay of the E5's can be laid at Intel's feet. They Apple screwed up the Mac Pro development process on top of that ... is purely Apple's FUBAR.
