For those with your head in the sand (PS4 DRM)

@starcraft: However what we can quite readily infer from both companies is that their DRM systems will be damn near identical.
------
We are inferring 2 very different things from the facts. While both have said the DRM is being left up to 3rd parties, MS has actually revealed how it will work on the X1. Alternatively, Sony has shown no indication of having a set up similar at all in regards to how DRM would work on the PS4. Now Sony could quite likely have set up a system (and that system could be very different) that would effectively be the same, but the evidence thus far does not support that such a system even exists on the PS4. Reportedly, there was a patent/copyright Sony was working on for basically watermarking blu ray discs, but have said that they won't be using that on the PS4, and for all we know could be for movies. Therefore we can infer that if Sony was in fact previously planning on using that type of system it would be vastly different in implementation, but effectively the same result.

So we have MS saying that DRM is up to the 3rd party games, yet they set up the system for them to enforce any DRM they might want easily and effectively.
Then we have Sony saying if a 3rd party wants to enforce DRM that's up to them to figure out how to do so.

That is the big key difference between the two in regards to DRM. X1 is already doing it, and PS4 is not (as far as we know and has been stated publicly)

So 3rd party games on X1 only need to figure out how much to charge, but for ps4 they need to figure out how to enforce such a system and charge for it.
