Who knows? Capcom has a couple of games coming out for both the ps2 and xbox and not the cube.
Personally, I want the ps2 version to sell at least ok. If the game bombs, and it's because it was a port of the cube version, this might tell Capcom to make the ps2 version first, and then, if at all, port it to the cube. We don't get many Capcom game as it is.
