As many people have said:
1) No.
2) No.
Let me explain.
1) I doubt MadWorld will make a profit, even as a Wii game. To then go into a $20 million PS360 game would be financial suicide. Nobody likes a port (with the exception of Zelda fans and RE fans, apparently). It would take at least another year and a half to change it from motion sensing to analog sticks, and it would kind of destroy the point of the game.
2) As I said, people don't like ports. Particularly not a port that has been rushed and badly made (as a MadWorld port would be). Perhaps it would sell a little better first week than the Wii version on the PS3 and 360. But it still wouldn't cross 500k on either system, while I think the Wii version (with Wii legs) has a shot at Zack and Wiki level sales.
