Ok thats definately the PC version they're showing there if it isn't CGI. If it is being done "real time/in engine" then thats the only platform that could achieve that level of detail.
The engine being used I pick is the "Far Cry 2" engine. Its a brilliantly designed engine with "layered shaders" So they can scale it easily between platforms.
Looks pretty cool and innovative, seems that we're getting a lot of new games this year and next which is pretty exciting. Its not MOH XXXX every year like the PS2 generation! xD
Tease.
