By the way, I don't think there's any denying that SB2 Wii bombed horribly - it didn't even chart. I'm pretty sure Capcom hoped it'd at least do that. I just think it strange that Capcom would expect it to do better than a budget-priced expansion on the PS2's significantly larger userbase.
Which illustrates some of the problems still afflicting consoles in Japan this gen - the PS2 is still around, and a lot of PS2 gamers who buy into franchises like Gundam and SB (though I don't know much about either series) are apparently content to stick with it for the time being. Which is a problem for Nintendo, because any multiplatform releases on PS2/Wii seem to invariably favor the PS2, which doesn't make a strong case for Wii third parties, and a problem for Sony because PS2 gamers apparently see no need to "upgrade" to a PS3 when a lot of popular games are still on the PS2.
