There are two questions asked in just about every interview with any prominent developer these days (and ones I did pass on while talking to Bayonetta producer Yusuku Hashimoto recently at Tokyo Game Show), questions asked because, well, people want to know.
No. Never. Ever. (for action games)
I dont ever want to mix up action games with Motion Controls.
Its bullshit. Dont need PSmotion/natal/wiimotion for it.
Just hand me a good old fashion controller so i can lie down and play a nice action game on a big ass HDTV :)
Leave the motion controls for casual games like... dodgeball.. or w/e.
Dont hurt your hardcore audience by this crap xD
