Well that blows but I'm still going to play it.
I don't have a gamecube, I'm not getting a wii, and my PC is not gaming capable.
That leaves my ps2 and 360, might as well play the one in 720
If your only choice is to play it on the 360/PS3 then don't have second thoughts and buy it.
A lot of people enjoyed the PS2 version of the game, but the main problem here is kinda what happened with Bayonetta; The game was made with a platform in mind and when is ported to other systems you can tell that the game doesn't feel and look right on the PS2.
You can only see this if you play the shit out of the game in GameCube or Wii tough. And seriously, Capcom haven't said anything about Move support yet? They are gonna lose sales because of that.
