Consoles need DRM to kill used games. Yes, some people will mod their machines to play pirated games. I suspect that's a vanishingly small minority of console owners, especially for the only console with a strong online gaming component, but that's what they'll point to, not the impact on used game sales.
But the thing is, DRM already won on the PC. Steam. Games for Windows and whatever EA's system is called are all entirely accepted by the wider PC gaming community as part of the experience. It's dressed up in digital distribution, but it's really all about ceding control to an outside party. There's no reason for Microsoft or Sony or Nintendo not to build the exact same thing for their respective platforms. Sony can safely put it off knowing Microsoft is going to take the PR hit at first. Microsoft can take the PR hit because Halo 5 will still sell 200 million units and drive dump trucks of cash up to EA to get an exclusive launch window on Call of Duty or whatever if that's not enough to get wide adoption. Once the console gamers have accepted the indignity, Sony can roll their scheme out and no one will even complain. It's not like gamers will really have a choice at that point, is it?
