Which afaik is no DX11 relevant feature though. At least I read a posting which was quite convincing and concluded, that tesselation is the only real DX11 feature - all the other things (which unfortunately often make next to no visual difference to the DX9 shaders) all were possible with DX10...
That's why I made my point: Most AAA titles don't support DX11 in the first place and many of those which technically do just use a feature like tesselation so they can put the DX11 stickers on their titles...
The first game that really makes use of DX11 might be Battlefield 3 as they seem to really have integrated it in the engine rather than using it as an "update" or small "add-on" here and there...
