New Gears of War 3 Trailer

Here's the new trailer for Gears of War 3 that just came out. Mostly a cinematic, but a few hints about how this game will turn out.

Gears 1 and 2 were both great titles, I spent quite a bit of time with both, especially the first one. Hopefully they will work out the multiplayer kinks prior to release, this time. Do I smell a Beta?
