Usually, they were the same sources. Sony rumors are desperate speculation while MS' are concrete... Come on dude. Again, I'm not saying it's real. Some of you are loosing it already over a rumor!
As for publishers... you mean the same ones who just recently publicly stated they have no problem with used market?
The same ones who said they'd strongly support the WiiU?
You think Sony lie to us back to back at E3, Interviews and everytime asked about this since Feb launch. This is BS, Sony clearly explained about everything, its only Third party publishers who can do something, if they do (thirdy party publishers)then I will quit those games because they are doing like this.
Sony's First and Second party games won't have anything like this so i'm safe which i'm interested in buying the PS4.
Look at these links which are from big sites which explains everything and don't be blind becoz xbone has this so you can damage PS4:
GAMING is not about spending hours to pass/waste our time just for fun,
its a Feeling/Experience about a VIRTUAL WORLD we can never be in real, and realizing some of our dreams (also creating new ones).
So, Feel Emotions, Experience Adventure/Action, Challenge Game, Solve puzzles and Have fun.
PlayStation is about all-round "New experiences" using new IP's to provide great diversity for everyone.
Xbox is always about Online and Shooting.
Nintendo is always about Fun games and milking IP's.
