There are an a lot of signs that we are going to get good news.
1. Yoshida making the joke about DRM (vita game) on Twitter. He isn't dumb... that would be pretty shitty if they were planning on delivering bad news.
2. OMGWTFBBQ's leak that EA is giving MS exclusives (games and DLC) because MS were pushing DRM and sony wouldn't commit to it (this was during the winter, if I understood OMG's post correctly)
3. Having not committed to it publically they've been able to watch all the feedback against MS - and then our protest - and then even more feedback against MS after they put up the website explaining it better. Can they really see all of that and think it's a good business decision?
Common sense is telling me that the PS4 will have little to no new DRM over the ps3. But, of course, Sony hasn't always been known for having common sense...
