Going beyond the fact that the guy is a PS fanboy (or at least a Wii hater as he has no praise words for the one motion controler that has an analog stick that he praised too)
Doesn't the Arc use a camera (for the ball thingy) and a wireless controler ?
That means, similar optical recognition lag as Natal added to wireless lag? (wireless means encoding, travel, decoding, it's significantly laggier than wired connections).
Do we have to add lag in hardware motion detection which the arc will use? or does it use only the camera, making it at least as laggy as Natal on the hardware side?
Even button presses coupled to electric signal in a 3 feet wire will lag more than light to 1 feet wired receptor.... the only lag natal can have is software recognition of the signal, and that is something that can be worked on by improving the code and/or the processing unit.
My point is, there is no reason for Natal to have a noticable lag once the software is finalized.
