Crysis 2: Everything about DirectX 11, 3D without perfomance-drop and 8-core-optimization
With NV paying $2mil I will bet Crysis 2 will have Tessellation.
I've not seen any mention of tessellation yet, from CryTek. Only their PolyBump technology. Which would be the obvious choice for consoles.
I'm not sure what they're going to do on the PC side. The game is near completion (or in fact, probably already complete as we speak, wasn't it to be released in November?), so it may have been too late to add tessellation support for Crysis 2, assuming they would be interested in it in the first place.
On the other hand, I would think that their PolyBump technology could quite easily be expanded into supporting decent tessellation. After all, the idea of PolyBump is to model high-res objects, and then have them converted to low-detail meshes with the extra detail encoded into bumpmaps.
Instead of bumpmaps they could create displacement maps, and then use tessellation to generate actual geometry, rather than just bumpmapping/parallax mapping to create the illusion of actual geometry.
Perhaps they could make an update to the PC version and add tessellation later.
