Pete Dodd's For Your FYI podcast brings up a good point. All of these "features" that MS had built to offset the negatives of their online DRM don't have to be completely scrapped. Family sharing could(and, imo, should) still be a feature for digital downloads. Used sales can still be implemented for digital games. There is some sentiment of anger toward the No DRM movement for forcing MS's hand in removing these features, but, ultimately, it is entirely MS's decision to remove them. If they kept some of these features for digital, they wouldn't lose all that hard work they put into building the system's infrastructure, they would just need to rework it. Keeping those features for digital would provide an incentive for people to purchase online, which is presumably what all platforms want anyway.
Anyway, oddly enough, this announcement has swayed me away from a PS4 @ launch. Now, I'll be sticking to my PC and "last-gen" for about another year.
