Eager for a bit more Project Natal news now that Jonathan Ross let slip what may or may not be a launch date? Then you're in luck, as MTV's Multiplayer blog has taken advantage of a recent Natal demo session to peg down exactly how much lag we can expect from the motion-sensing system (assuming it's not fine-tuned any further, that is). After timing some 40 movements with a stopwatch, the site found that "life-to-screen" transitions ranged from 0.08 seconds to 0.12 seconds, or about a tenth of a second on average. That's obviously a bit slower than the response of an old fashioned controller (or even a Wiimote, for that matter), and is just enough to be noticeable when you're playing. Of course, it's the games that will ultimately matter the most, and we still haven't seen much more news on that front.
