Nah, I got my PS3 late in the gen, and there's still plenty of games out there. I just bought Afrika last week. I probably won't stop buying (mostly old) PS3 games until at least midway through the new generation, and with all the games currently and coming out, it'll probably be even longer until I feel any interest in the PS4.
