Who knows if Sony didn't have the exact same measures planned (always-online, used games, etc.)?
As far as I recall, those points weren't adressed at all during the PS4 presentation, but once Microsoft came out with it's self-destruction-tour, Sony was suddenly spouting out all this "We won't do this, we won't do that" statements, using the backslash to come out on top.
Maybe Sony was just wise enough, to wait for the competition to reveil their plans to tackle these issues and then, seeing how the possible customers reacted, resolved them silently, since they couldn't afford to go down the same path as Microsoft... I mean, looking at the price for the new PlayStation says rather much already.
What I'm saying - if Microsoft wouldn't have made a try to get such measurements into the console market, someone else would have done it. Perhaps not now for this generation, but sooner or later someone would have had a shot at it.
Thankfully they changed these requirements and policies before the consoles hit the market, now the PS4 at least has a potential competitor... with that said, I'm still not sold on either console at all, even after seeing all the E3 footage.
