Traveller's Tales' director Jon Burton thinks that Natal "lag issues" could have an affect on the peripheral's chances of success.
"I was actually more impressed with Sony's motion capture solution than Microsoft's Natal," he told Develop magazine. "[Natal is] exceedingly clever, but the lag on the input and lack of physical buttons is really going to restrict the kind of games that can be done with it."
Discussing Sony's motion control (still without a snappy name), Burton added, "Sony's solution will be cheap, accurate and will put buttons at your fingertips, meaning everything from action adventures to FPSes can be handled with the same input."
Do you think he's got a point?
