I won't consider copying as the right word to use, is more like utilizing. Sure nintendo come out with the idea, i got the wii, but i am really disappointed with the number of games they come with or the 3rd party come out with, not to mentioned is not in HD. I am not really a graphic type of gamer fyi, but with today tech, it would be much fun to have things a bit on par to compete. With only the motion, is really not enough, while they keep milking with the balance board (which obviously more toward exercising?) which is not really into a gamer market.
I been with wii and play numerous games from it, but most of it are truely waggling feast, with 3rd party come in with least quality titles which focus on sport, sport and sport.
I played RE4 on the wii, truely awesome, the control is perfect in my gaming history. I am all hype to see more of this kind in PS3 move, being socom demo for the start, i believe more will come, like RE5 alternative for those who havent played it yet. Not to mentioned the other sport games on a much realistic environment and avatar rather than cartoonish backdrop.
All in all, I am counting that this time, sony do it right to futher enhancing the capability of motion sensing in gaming, and shall exceed wii performance, with more 1st and 3rd person shooting games, sport games, strategy game (for console finally), and also RPG!
In short, Nintendo created it, Sony hopefully will enhance it.
PS: Uncharted 3 to fully utilize the PS3 Move

yah yah....
