technically it won't be Sony screwing you it will be Sony telling the publishers they can police themselves. then Sony will kick back and say "hey we didn't tell them to do that, we don't require internet on the box itself so what they do is on them."
don't think for a minute that these publishers are gonna have the Xbox locked down tight all the while open season on Playstation and don't think for a minute Sony is gonna stand up to them and tell them no DRM.
there's a phrase for what Sony is about to and has already said they're gonna pull;
Plausible deniability.
yes it will, sony could just tell them to fukk off and suck a dikk like nintendo did. Atleast Microsoft manned up and implemented a policy where our used games can ATLEAST be used on other system. if there is no daily drm authentication there is no sharing between systems plain and simple.
Almost all publishers will use that policy besides maybe CD Projekt
