I'm not dishing out 600 bucks for the new PS4 whenever it comes out, besides, these current consoles aren't really outdated...
BUT DUDE! Play the second one, it's pretty sweet. I recommend getting it on ps3, I have for both now, but originally played it on the 360, controls are pretty fucked for driving, but other than that, it's a solid game with lots to do. Just wish they would make multiplayer similar to GTA where you can roam around if you wish.
