To a certain extent, it makes sense for third parties to attempt to make the XBox 360 somewhat popular in Japan in order to produce greater competition between the console manufacturers.

Their PS3 sales weren't quite as high as expected in Japan - only sold 300k when they expected at least 500k.

Hence their attempt to recoup investment by porting to/developing for the 360.

Actually, IMO I think the game sold quite well. 300k for a userbase of less than a million means roughly one out of three PS3 owners in Japan (plus a couple of importers here and there) have bought the game.

I think that's not too shabby!

Are they actually releasing it in Japan or just North America? With 360, I wouldn't be surprised if North America's better anyway, though it could use a good publisher.
