PS3 has more interesting western style games:
Killzone2,Uncharted 1&2, Wipeout, MAG, Resistance 1&2, MGS4, God of War 3, heavy Rain, you have Forza so you should also like GT5
Wii is all about motion controls (which you will get for both ps3 and kinect as well) and Mario/Zelda/Metroid with most of good games on it either being japanise or niche titles.
Also PS3 is at similar level to X360 in graphics with Wii you would downgrade yourself to SD.
If you liked japanise games it would be tought choice but since you don't ps3 hands down.
