This is the Bioware presentation of Mass Effect 2 at E3. If anyone can tell me where Shepperd pulls his massive cannon from at 2:43, kudos to you.

Microsoft uses a similar technology as Sony for their new motion controller but seems to chose for a different approach in selling it to us. First off, Microsoft's version does not require you to use any controller in your hand, it all works through the camera in front of the screen. An interesting take but we wonder how the camera will distinguish between two players excitedly flailing their arms through the air while they are in a race or in a fight to defeat a horde of angry orcs... The presentation is geared more towards family as well as communication with the Xbox and with others -through- the Xbox.
