Yeah, they said this from the beginning but people didn't want to listen.

They won't implement it on first party games but third parties can if they want, meaning whatever multiplat has DRM on Xbox One will have it on the PS4 version as well.

Dont talk rubbish all games have DRM on xbox one with no effort or cost to the publishers, only those willing to go out of there way will bring DRM to PS4, judging by how little 3rd party DRM is on PS3 even tho it is possible, im guessing we wont see much at all. Unless Sony has put a system in which is easy for 3rd parties to use, which now seems highly unlikely if they had no plans to use it themselves. 

Exactly. This is all we know right now. Sony isnt implementing DRM but so far it seems they are leaving it up to third parties. This could be mended further before E3 because Sony is known to listen to consumers where their consoles are concerned, if at all definitley better than MS. If third parties implement it, it will be a wall like Origin and the online pass system which will track EA's games.
