Pencil Koei Tecmo's name in for a company that is interested in Sony's new motion controller that was introduced at this year's E3.

"I'm sure that for casual games these motion controls will be very popular, but for action games like Ninja Gaiden we need quick responses and if you're swinging your arms around like you're using a sword you will soon be tired," says Tecmo Koei honcho Kenji Matsubara.

So no Ninja Gaiden with Sony motion controls?

"Maybe we have to change the playing style and check the technology to see how quick it can be," he explains. "So, at first it will be casual games and then maybe hardcore games and we have to prepare for that and provide the games to satisfy that playing style."

Kinda hope this doesn't mean casual Ninja Gaiden with motion controls.
