More than 2 hours of footage from the PlayStation 3 version of Diablo III are available at the PennyArcadeTV YouTube channel, showcasing some 4-player co-op. The footage shows the beginning of the game, and seems to be meant more as a Let's Play surrogate rather than a preview, with a camera constantly pointing at the players, so be prepared for some less than informative commentary and all the things that usually come with Let's Plays.
