I know what you mean and remember that thread quite well. However, I am still concerned about the future of Mac Pro and must look long term for my investment in software. As mentioned in that thread, I am a 3D artist and use a lot of high-end software that costs well over $5,000 plus upgrades per package. It would be nice to see some sort of statement one way or the other from Apple on where they are going instead of dragging things along guessing.
One other problem as I mentioned in the prior thread is AMD itself. If it is very top line graphics card that will be fine for most users, but 3D software tends to take better advantage of nVidia and their "CUDA" cores. When rendering, if that translates into speed difference or even the way a scene is constructed, then it will effect both my time and money. I was hoping to see nVidia back as an option, but it appears still AMD only.
It's not a matter of wanting to, but like I stated above it comes down to investment cost for the future and right now many are leaving Apple going to Windows for their 3D and CAD needs. You simply can't wait 15 months or more between new equipment or even graphics cards if you are in those fields. Unless there is a firm commitment, I too will be forced to make a decision in 2012 and it could be the end of the Mac era for me.
All of the PC workstations that use Xeon (Lenovo and HP z series) are waiting for the next Xeon rev, not just the Mac Pro.
And I would disagree with your premise that "many are leaving". If anything, I'm under the impression that Mac Book Pro's with Parallels is a popular choice for a PC workstation replacement, providing you don't need a Quadro or FirePro graphics card.
