They have personalities in Japan versus big name publishers. That's something they're still lacking, at least as far as we can see now. Namco, Konami, Capcom, Sega etc. have voiced their support for X360, but that much is a diplomatic given. Xbox got support from all of those publishers, but it wasn't very meaningful. So hopefully things will be better with X360.
Talking to small startups with big personalities is a smart move, of course...they'll obviously be far more open to MS (and their money) than the larger publishers might be.
