PS2 versues PS3

I don't know if I will be able to get a PS3 since the business I pre-ordered it from doesn't know if they will be able to get them. So if I can get it, maybe I should sell it on ebay. If I can't get it, maybe I should just get a PS2. They are a hundred and thirty dollars, and 20 dollars a game. That's about as cheap as they are going to get.
