Yup, I'm seriously debating cancelling my pre-order. I am not a serious gamer, I am a casual gamer and I like to play most of my games alone, not online getting my ass beat and made fun of.
It actually pisses me off even more right now that PS4 doesn't have backwards compatability. I'd just go back to my other GT game. I bought a Playstation for Final Fantasy many years ago. Lately Sony has been doing more and more that piss me off the way they treat their gamers, and how they handle their ecosystem. I'm really closing to jumping ship and moving to Xbox. I've already made it clear to the family that if the next Playstation isn't backwards compatible, we are moving to Xbox since we'd just be dumping all our old games in the trash anyway...
