"Sony won't provide backwards compatibility support for PS3 games, which can't be seen a huge surprise given how such functionality was phased out of the PS3.
And most controversial of all is talk of locking games to a PSN account in an attempt to strengthen new game sales. You'll need to be connected to a PSN account in order to play too. Trades will be allowed, but anyone buying that pre-owned copy will be offered a limited version - similar to a trial - which can then be unlocked for a fee."
Sounds like they are planning not to shoot their selves in the foot this time around. Both knees sounds more accurate.
Let's hope this rumor ends up false.
