I'm not getting it because the demo didn't convince me it was worth the investment. Then I watched that 10 minute intro cutscene and gameplay video on Youtube and if anything I was less inclined to get it because of the really cheesy dialogue and the intro didn't seem to indicate much of a story.
After the interminable load times I've had to suffer with Neverwinter Nights 2 I doubt the Bayonetta load times would put me off. So if the game really interested me I'd buy it and as I don't have a 360 and don't plan to get one I would have bought it on PS3.
Outside of Japan I'd say this game will sell 2:1 in favour of the 360.
