Devs aren't stupid. I mean the 360 userbase in Japan is well not enough to get any sales profits. Meaning every project has to be multiplatform with PS3 almost. And if it's a heavy Japanese game it's even more risky because can't count on American. Then you got the PS3 which takes a lot of money to develop on and time, and for a userbase that is not very large, a third the size of the Wii's. I mean it's hard to win in Japan for devs when they stay on PS3 and 360, just for those reason, especially if the game has little outside appeal, like Monster Hunter.
Then there's the Wii which has seen dominant first party sales with few third party games selling well. Although most of this has to do with not brining top name brands to the system, and when they did they were well pathetic, especially in Japan where alot of the Wii owners which are probably the dominant buyer by a longshot. Thus you didn't see a lot of support but mainly as a slap in the face at their own mistakes. But now you are seeing more devs start to go that way mainly because they have no other choice and because even if the game doesn't sell well there is still less risk than if it had been put on PS3 or 360, especially if it's Japanese only kinda game. Thus this is really no surprise. Japanese market is kinda a bad spot for 3rd party devs right now, but I think they can flip it around simply by giving the Wii better games, and MH3 should show that.
