I'm sorry, but you can't expect every ps2 owner to buy a ps3. you have looked at it from the side "why shouldn't I buy a ps3 after I had so much fun with my ps2" but this doesn't work. it is more "why should I get a ps3 when I still have that much fun with my ps2?" and what follows out of this question is: "oh, it sounds funny to play by really making the movements. why shouldn't I try this?" You have to remember that the biggest part of your 111m ps2 owners are casuals. they don't care about sony, nintendo or microsoft, they care about fun.
