Did you guys notice that all of the latest Mass Effect 3 footage is from PC version? You can tell because of the hotkeys in the upper left corner. Developers usually use Xbox 360 to show off their games. There are several possible reason for showing us PC version. I narrowed it down to 2 most likely possibilities: PC version will be Origin exclusive and they want to hype us PC gamers to give in to the dark side (not gonna happen in my case); PC version looks significantly better than console versions (graphically) so it's normal to advertize the best looking version. Knowing EA it's probably both.
