There probably is since Sony is banking on the PS3 being around for a while. The only problem is that if developers can't tap that potential, it becomes void and useless.
So far I haven't seen anything that would make me buy a PS3 just yet. Blu-Ray isn't THAT important and the games just aren't there yet. Neither is the online system. Xbox Live is YEARS ahead of the PlayStation Network in terms of services and features and the only enticing thing is the free price tag. Heh, don't even get me started on the Wii's online system...it's like bringing a stick to a sword fight.
