I can see this happening if SONY pushes 3rd party developers to do it and i see lots of games doing this. I mean look at Madworld -- that would easily run on PS3, it would be cheap to port over and it would reduce the risk of doing such a game.
Ofcourse the bad side is that you can bet that alot of the minigame collections / shovelware on the Wii will be ported to the PS3...
It is a shame though that most good Wii games are published by Nintendo (or are old games like RE4 or Okami)
