IGN has published a video of a CryEngine 3 demo from Crytek. The clip features Xbox 360 and PlayStation 3 footage.
The video is meant as a tech demo only, so the fact that it features nanosuit-clad soldiers from Crysis running around doesn't necessarily mean anything concrete. It could just be that Crytek recycled some of its existing assets. No titles have been officially announced that will be built on CryENGINE 3 as of yet.
