Come on Vurbano. The title is misleading. Its not 8000 wont play, its some have issues and some wont play.
"For instance, the PS3 might not play background music to the popular "Tekken 5" combat game, and some scenes from the "Gran Tourismo" racing game might freeze, according to Sony. The game "Suikoden III" can't read data from a first-generation PlayStation, while a virtual gun in one of the "Biohazard" games won't fire properly.
Some older games won't run on the PS3 at all, according to Sony Computer Entertainment spokesman Satoshi Fukuoka. Online upgrades of the PS3 software will be offered, but it's unlikely that all the problems will ever get fixed, he said."
Keep in mind, Xbox 360 is not compatible with all Xbox games. There is a list and its got most of the popular ones but this is not a strange occurance.
