So an RFID on the disc itself would prevent used game sales. No internet connection required. Thats not how I imagined RFIDs would be used, Skylanders just stores your levels and stuff in your character's figurine.

RFID stuff is evolving for different uses pretty rapidly.

For instance, in some retail stores they're experimenting with tagging all products to allow for easier access to take inventory and to cut down on things like shoplifting (though if someone's determined enough, they'll obviously figure out a way).

The only thing that worries me is if this is introduced mid generation and is defended by Sony as "we don't mandate it, it's the choice of the publisher" a lot more people would accept and defend such a practise then.

Eh, looking at something like eShop prices for Nintendo's digital stores (where this is the case), I don't think that approach holds any ground with a majority of consumers. They'll be against it.
