I never even bought a PS3, so I doubt I'll buy a PS4. Any games that I cared about came out for other consoles I already had. Specifically, I try to get PC versions of as many games as possible, because the PC often plays the game better and I don't have to have 3 consoles. I went without even a 360 for a long time. Just me, my PC and my Wii.
I hate the concept of DRM, but to completely honest it doesn't really affect me. I never pirate games, so I don't have to worry about that. My internet connection is usually pretty good, but if I ever visit my parents with their satellite internet, I'd be screwed if the game required an internet connection and used up more than a bit of bandwidth. It's still pretty unfair to require an internet connection to play a single player game, because I know all too well what it's like to be in an area without decent internet.
My biggest beef with it all though is the inability to buy used games. That's a real jerk move. I have a lot of used games I've bought over the years (mostly for very old consoles, like the SNES or SEGA Genesis), and while I never sell my games, I'd like to keep the option to buy used games. Even if I usually wait like a year to get stuff when it's already cheap. What if I can't find new copies any more? I suppose things like Steam kind of eliminate that problem by having the game always available in electronic format.
I somewhat doubt that the DRM is going to be any worse in the next generation consoles though, or if it is, I doubt it will be so tightly integrated into the console itself. I'm not sure that the bad press would really be worth the gains to the console manufacturer. It might not really damages sales all that much, though, so maybe so. I'm sure their marketing departments have done their homework.
