Unsurprisingly, this will be for Windows Vista and "future versions of Windows," but not Windows XP.Let me rush out there and buy Vista so I can play dx 11 games. After all, look how how many dx 10 enhanced games there are out there that actually have a noticeable difference between dx9 and dx10... I have to beat the run on the stores for Vista so I can be first in line and not risk Vista selling out after this momentous announcement. I'm scared, hold me.
