It's GAME ENGINE FOOTAGE not INGAME FOOTAGE (Score 1)

Don't think this video shows something that will be seen in this quality in the later game. It is only a demonstration what the engine CAN do. Scripting, many expensive connected - via SLI or Crossfire - gfx cards will show you this kind of footage. Think of the "INFILTRATOR"-demo of the UNREAL-Engine. This one also shows nice sf-centric engine footage - but not real ingame footage. You will need 4 connected 980gtx cards to render this big scripted scene.
