Jon Burton, director of Traveller's Tales, tells Develop that he was more impressed with Sony's motion controller than Microsoft's full-body camera device for code-named Project Natal.

While praising Project for its cleverness, Burton expressed serious doubt in the peripheral's ability to play a wide range of games. "Lag on the input and lack of physical buttons is really going to restrict the kind of games that can be done with it," he observed.

Microsoft has been pushing Project Natal to developers behind the scenes, hoping to stir up interest in the creation of exclusive titles. Big publishers such as have eagerly come on board, but Burton's scepticism could be worrisome for Microsoft.

Burton has more faith in Sony's motion controller, which is slated for a spring release ahead of Project Natal that is tentatively set for autumn 2010.
