eventual DirectX 10 / 11 patch, possible increase in performance?

[Jinko]

One of the major additions of DX11 is tessellation and the engine has to be written specifically for this, it would require a lot of work on SE's part, all existing models would need to be redone to allow for proper tessellation also.

Somehow I don't see SE investing the time to do this, at least until an expansion is on the cards and the game is more successful.

They would basically be adding another layer to their Q&A as well, making sure that the game runs on all versions of windows as well as all versions of Direct X. (or yea and PS3)
