While I would appreciate higher-end titles, Video Game Companies are always going for money. I don't really see how any game like Monster Hunter could benefit from the Wii Remote, but who knows what they're doing? But the Wii Remote probably has very little to do with their reasoning for making it for the Wii. Like you said, the Wii is more popular in Japan, their strongest fan-base, so their's more money to be made. But it's no lie that the PS3 costs more to develop for, if you want to stay on top of the competition there. The end result, of course, is less money spent.
