This is the Tom Clancy's Ghost Recon: Future Soldier trailer that Ubisoft showed in their E3 press conference. Shoot enemies through certain materials, scout using the portable drone, use timed explosives, kill using melee attacks, and coordinate all of that with your team-members.
Although this is all CG, the gameplay that was shown at the press conference looked about what you'd expect from a "future" update to the GRAW series. It wasn't really mindblowing, but it looked like a fun game to play with a couple of tactical-minded shooter friends. And it has Kinect support, which makes me wonder how that will work if the Kinect microphone will also pick up your online banter.
