Project Natal made big waves at E3, arguably more than the PS3 motion controller, soon after both press conferences announced their respective projects many debates were sparked as to which tech was the superior one. Both "controllers" are fairly different and it seems that the two are going to be targeting different markets.
Fresh from the thrills of E3, the gaming community is now very excited about the new motion technologies shown by Microsoft and Sony. The problem is these technologies won't be released for over a year, but you can pick up a 1:1 motion controller today with Nintendo's Wii MotionPlus.
