DMC4 was announced as a day-and-date title in Japan, as well as NA/PAL a few months ago (along with the whole Lost Planet PS3 thing as well).
Either way, MS can get a good niche following in Japan. As much as some clamor it's useless, it's not. Microsoft needs more Japanese titles, not only for Japan's sake, but Taiwan and Korea, which have similar interests (thus the partnering with Phantagram).
And beyond this, MS still needs Japanese content in the US and PAL. I wouldn't be a X360 gamer if it wasn't for Japanese games on the X360. There is a huge US and PAL userbase that will be buying your various Japanese-made games. And they'll buy them for whatever system is the best/cheapest. If Microsoft can make sure they're in prime position for those sales, by parnering with more Japanese developers, the better.
Back from the dead, I'm afraid.
