If you haven't been able to grab the video on XBLM, or if your slavish devotion to X360F prevents you from checking it out on Joystiq, here is the recently released Mass Effect video. If I am not mistaken, it is rendered using something called "streaming" technology. Simply amazing.
So, if you've got four minutes to spare, sit back, relax, and enjoy the show.
Update 1: Replaced not working Gamevideos video with reliable Youtube. Sweet.
