I think the vague responses and "answering without really answering" tactics we have seen by Sony would suggest that yes, what you see in terms of used games DRM on Xbone, you'll see on PS4 as well.
The only difference would be Gamestop might not have to jack into Sony servers just to buy a game off a customer like they would on Xbone. But publishers can take care of that easily enough with a serial number included in every game. Or, the disc based solution from this thread, which doesn't even require Internet.
