PC will survive but not in it's current form. It should become a bit more POWAHFUL. Now lets talk about that POWAH for a second shall we? Games are already dumbed down for PC's. Need proof? World of Warcraft. The graphics are weak when compared to recent games on the previous generation of consoles. Oh...and PC owners have been claiming that same bat-shit crazy PC all-knowing, all-seeing, master-race crap for years. When pc games come out which are not dumbed down, you'll be spending more money to upgrade your gpu or entire laptop to be able to play those few games that need that POWAH! I like my pc games too so don't get me wrong here. I'm just not afraid to say that consoles have some advantages that PC's don't have. Having the biggest baddest machine is a constant preoccupation of the PC zealots mind. I wonder if they are compensating for something?
WoW has its moments were it looks really nice with max settings. That being said.. the reason Blizz hasn't made a huge graphical update is because people need to be able to play WoW on a potato. And that's the reason why the game has been as popular as it is for this long. It's easily accessible.
But don't let that fool you.. 25 people fighting a boss with max settings will slow down even the strongest setups.
