Even if the PS3 comes out with better games in the next two years, I still highly doubt that its' price will be reduced down to the point where the mainstream masses can afford it without a problem. It will cost $200 within 2 years? That doesn't even sound anywhere near probable, more or less, even possible to me.
Right now, the only PS3 game that has my attention is MGS4: Guns of the Patriots; everything else, I could care less about. Even Final Fantasy is starting to become really un-appealing and pointless to me.
