A seemingly harmless report from UNCTV in North Carolina on the local video game business has an unexpected treat: quite a bit of footage of people playing Gears of War 3's multiplayer.
It's scattered throughout the clip, so there's no one single spot you can jump to and see it all, but there's plenty of it, and considering it's off-camera footage it's not bad, either. You can clearly see some new player skins and new levels, for example.
Gears of War 3 was supposed to be out in April of this year, but has been pushed back to at least the Fall. Meaning this might be the last look you get of it for a while! Well, at least until the Game Developers Conference in late February, at any rate.
