I'm a little late since I just returned from NYAF last night (more on that in a couple days, hopefully), but an expected-yet-unexpected bit of news dropped Sunday morning, that Mushihimesama Futari 1.5
(it's a Cave shooter) will be released to the Japanese market without region coding. That makes it, to my knowledge, the only Japanese game that will work on 360s that are not coded for that region. (Game regioning on 360 is optional; up until now, all Japanese 360 games were locked to only the J region, whereas the vast majority of North American 360 games work in both the U/C and J regions. PAL is probably screwed over.)
All the news sources quote Cave saying this is a test to see how successful the game is with the software restriction removed. The hope is that if this makes them a lot of money, we'll either have future releases continue to be region free, or we may see localized releases at what would hopefully be at a price point more people are willing to bite at. And the game is doing pretty well, judging by the fact that after only a day and a half the game is #3 in Play-Asia affiliate sales - behind only the latest two Pokémon variants.
Oh, and above all this, it's supposed to be a pretty good game.
