Square Enix CEO, Yoichi Wada, has told the Financial Times that the impact of motion controllers is 'quite limited". Speaking at TGS, he said:

"Present game machines already have a lot of functions: they are a network terminal, a Blu-ray or DVD player, and a gaming machine. Compared to these three pillars, the [new motion] controllers are quite limited, so the impact may be small. They are an extension of the gaming function."

Limited they may be, however, Wada saves some praise for Microsoft's Project Natal, saying: "As a user interface it’s fantastic and I think it will become standard."
