NVIDIA can only stall adoption, not prevent it. Look at the hits NVIDIA takes in games with deferred shading... up to 68% in Bioshock on the GTX 260. If Bioshock were DX10.1 you'd see the same 14-24% AA hit on the 4850. Eventually, almost all games are going to use DX10.1 and deferred shading, that's a promise. When that day comes (probably by this time next year), assuming it doesen't run out of video memory, you'll see 4850s beating GTX 280s any time >= 4xAA is used. The only way this projection could be wrong is if NVIDIA has undocumented support for DX10.1 based shader AA.
