Sony's PS3 has not been hacked in a way that pirating games is an issue.
Kmiller's projection is unfounded because Sony's bluray encryption, proprietary hardware, etc has proven itself. They've probably got better non-invasive DRM concepts in the pipeline, but as things stand... try hack a PS3. You won't enjoy the process or get much out of it.
The concept Kmiller is throwing around about PS4 DRM sounds hokey at best.
I may have over-exaggerated PS3 piracy, since I've never looked into that scene too heavily, but there still was the PSJailbreak which allowed for pirated game to very easily be played on a PS3. It obviously only worked on older firmwares and has been patched out, but for those people who have stuck around with the old firmware, and slowly upgraded using CFW are still able to play recent releases. For the proprietary hardware, sure that was a huge advantage to reduce PS3 hacking/homebrew, but with an x86 architecture, instead of the 7+1 custom cell, do you really not think it will be much easier for people to break into these systems?
As for my PS4 DRM, I truly hope it is just a concept, and that nothing like that is forced upon people, but like baldguy said, look at the past, and in the past EA pulled that bull**** "Online Pass" and why wouldn't they try it again with the new consoles? Now obviously Sony came out and said that yes, their self-published games would be free to exchange discs with friends who want to play, but Sony only publishes so many games, the rest will rely on third-party publishers to enact DRM however they see fit, either by not implementing it at all, or going balls to the walls forcing a constant internet connection (I think this only affected some PC games).
Now straying away from previous topics. Something I really hope to see is an Xbox One.2 or PS4+ in 3-4 years that utilized the freshest AMD APU's with more upgraded x86 and GPU architectures, since they are now using a constantly expanding architecture instead of custom ones that are never advanced throughout their lifetime (performance wise, I know the X360 chips were massively shrunk throughout it's lifetime). With these architectures, I wouldn't be surprised to see if this is one of the last console releases ever from these two. Since like I mentioned above, they just have to release upgraded APU models, and game designers only need to throw a few more GB of textures on a disc to make it look even better for the consoles that support it. That is of course assuming that x86 or AMD won't be dying anytime soon.
These two new consoles excite me very much, and I can't wait to see what kind of things they will bring to the gaming industry.
