... here's a decent preview! The newest trailer to promote Bioware's latest game is done in live-action, with real actors. You can see Shepard for a few seconds during the end. It's not an A-list actor, but it definitely looks like the Commander. The content of the actual trailer lacks a bit of substance, but it's moody and is sure to get you that much more excited for the game.
Mass Effect 3 comes out on March 6th.
