That's some weird PSN save locking thing that Sony implemented for the PS3 that wasn't well received, I never saw it on more than a handful of titles. Some games were locked to your console, some to your PSN id. There was a game that was region locked for the PS3 as well, I forget which one but oh well. The PS3 in general was a mishmash of poorly executed concepts, it's amazing it managed to do so well. Stating that the PS4 won't be able to do those things based on it is pretty silly, they have a twitter account they actively respond to so if you have some concerns just ask for clarification.
