Phil Spencer, head of Microsoft Game Studios, talked to Kotaku recently and had a couple of words to say about upcoming Japanese projects...
"We have signed some things in Japan that we haven't announced that we'll announce in ... 2014 so that people get to hear about support in Japan."
"The creative teams in Japan have always been top notch. And yeah, you're right that we've never been the top console in Japan, but the support that we've received, either from publishers like with Capcom and Dead Rising or developers is always great."
"We kicked off our independent developer program when were at Tokyo Game Show and saw some top talent walk through the door, so I think you'll see some indies too ... I'm committed to the development there."
Microsoft have yet to announce launch plans for Xbox One in Japan, and perhaps it would be good time to announce some of these Japanese partnerships when they decide to do so.
