I think it is because console support is all over the place. Since there is no clear market leader (they don't treat the Wii like one) the consumers have to go to one too many consoles to get what they want.
Even worse, these Japanese games, have just been....bad. I mean, the games from established franchises have been good, but I don't see any new stuff catching fire.
