The Wii is more powerful, i don't know exactly by how much, but its not by "GREAT" deal, non-the-less its more powerful.
IMO nobody has really tap'd the wiis real power yet, Another M looks to be the best and so does MHTri but thats about it.
Chaos Legion would look the best on Wii i think if it comes on for Wii (as-well as PSP)
So in conclusion Wii overall is more powerful but i dont know by how much because PS2 does have some nicer looking games then wii. valkyrie profile 2 silmeria and the original chaos legion for sure.
But... As for PS2 VS PSP, im willing to bet PSP games look better then PS2 games now.
