Graphics whores will always focus on graphics and it's easier to sell a game on graphics than it is FPS, so in that sense I agree that 30fps will always exist.Im afraid 30 fps will always exist
Newer game with more advanced graphics will always comes and push curent gen console to 30 fps back again
When the consoles comes out they might be able to do 60 fps on the game that comes out during those times just fine but years latter when newer game with more demanding graphics arrived due to its limitation the console will have to scale back to 30 fps or worse again until nextgen console arrives
That doesn't mean they should.
