PS3 rules! It has the most advanced and powerful graphics processor ever developed.
Though mine is more like a Bluray player with a game system built in than the other way around.
Wii has no HD. Sux on a big TV. Wii also can't stream Netflix HD.
My son has his own PS3 and loves the PS Move as well. I have to be careful playing that with him because I have no cartilage in one spot in my shoulder. I reached back to swing a hammer at him and hit that bone on bone spot. Hurts like hell. He laughed because just as I let out a groan from the pain he hit me with the sword. Perfect timing. :D
