If I was to take a gamble I would say natal would make a greater impact than arc.
At the same time having a motion controller gives developers far more options in certain games.
As I said before and I'll say it again. Sony can easily implement a natal like system for the PS3.
Natal is promoted as controller free. "No more controllers" is the natal slogan...or something like that.
The result is that PS3 can be classical, wii like and should sony choose to do it, natal like.
X360 can only be classical or natal like.
From this I gave the PS3 the edge as it can potentially "do everything".
Time will tell but natal has more going for it as it is a "new" concept.
As for those of you who go on about copying, please. There is a thin economic line between innovation and copying and $billions are made doing both.
MS "copied" Sony and release a console. Sony copied the wiimote...and nintendo are always copying my ideas.
