What is interesting about a simultaneous release on Wii and PS3, is that it will tell us for sure what platform the fans of such a genre generally favor. If a sizable demographic of Musou fans now own both a PS3 and a Wii because of SSM5 and SM3, and the fanbase of Basara is a sub-set of Musou fans, then the question is - given a choice between a PS3 and Wii release of the same game, if they have both systems which would they pick?
I think that's a question we can probably answer right now- why would anyone pick the Wii version? I assume the PS3 version looks somewhat better, there is no control difference, and at least in the West the PS3 version offers online. There is zero incentive to buy the Wii version IMO..the only sale swill come from Wii only owners.
