It could be that dx11 is being held back for the release of this new nvidia card, after all nvidia did pay crytek 2 million for crysis 2 to take advantage of its video cardds as shown here in this article.
So before we go blowing up at crytek for not having all the features we might want to see what nvidia does first before we crucify crytek
