Even if it was just DMC with a chick, I'd get it. The man who created Devil May Cry (and Viewtiful Joe and Okami) also made this game.

It sucks that the PS3 version in Japan was technically inferior, but all reports say that it's still a fine game. So if you have a PS3, and even if Sega doesn't 'fix' it, I don't think you should be too worried about it.

The last DMC game did pretty well from what I recall, but this does not have the brand recognition behind it. Sega's doing a much better job of advertising this than they did with either Yakuza or Valkyria Chronicles, so I hope this game does do well for them (and Platinum).
