I don't know alot of people with PS3s, nor do I know alot of folks who play the games I do, so I'm really not at all concerned about resale, and the case would probably remain the same with a PS4. What I do worry about is owning hundreds of dollars worth of games that can't be played because the only system they're allowed on was damaged beyond repair in some freak accident.
But that's if they get the patent, and if they actually implement it. They have a few other patents under their belt that would displease the general gaming public, but have wisely opted not to implement them. There has been nothing but backlash on this particular patent, so I'd be pretty surprised if it actually went through. Their commercials-in-video-games patent is far more likely to make it onto a system. Until the system is ready to release, though, I wouldn't put too much thought towards it.
In the end, it's their perogative. If they want to flush their business down the toilet, let them. I can think of plenty of other things I'd be happy to spend the console/game money on.
Well, conveniently I wasn't planning on getting a PS4 anyway. Glad to see my faith in the PC was well founded. Now Linux just needs to start making itself user friendly. *begins laughing very hard at the last sentence*
TF2, Counterstrike, Starcraft, XCOM: Enemy Unknown, Amnesia, STALKER, Crysis, the Witcher, Total War, Civilization 5, ARMA2, The Old Republic, Penumbra, War Game: European Escalation, just to name a few. Then you get the best multi-plats at generally higher quality than they are on consoles.
I personally suggest you get a PC, since 99% of XBox/PS3 games can be plaid on it, and Nintendo systems so you can get their exclusives too.
