If Xbox could run Doom3 & HL2 is it impossible Wii could run 360/PS3 games?

[Killzone3]

You will NEVER ever see the likes of FF MGS4 Gears Killzone GTA4 done on the wii.

If the devs make a weak PS3/360 game then it might be possible. If your looking for ports for the wii, its getting plenty from PS2/PSP.
