While i do believe this is dirty underhandned BS from a company on a long and HUGE decline (which is very fun to witness!), I think the next consoles will most likely favor online downloads anyhow so this will probably be somewhat moot.
Anyhow, I'm sure the major publishers will have a say and they're the ones likely to decide the fate of this type of tech.
Christine, when you buy a blu ray you are paying royalties to about 20 companies and Sony is only just one of them. Its was a fallacy that blu ray was "all Sony". Blu ray was developed and founded several companies including HP, Panasonic, Disney, phillipis, pioneer, hiitachi, samsung etc. etc.
BTW, I bet the MPAA would love this tech. for blu ray movies!
