Next generation consoles will only go uphill if the graphics are similar to what happened from PS2 to PS3, in order for them to start coming out, they will need to release 3D TVs that are higher than 1080/1920 pixels, that's the only way it will come out with more features and things to enjoy, and I'm talking about a major graphics improvements, for PS4 games they will be able to make games like MAG 2 and make it so they no longer have the old cartoon look to it, graphics and sound will be as realistic as BF3 in ultra high definition, and the game won't lag at all (just a prediction) and of course all games from previous consoles will most likely be compatible with the new ones since what the guy said above, the good games are already made, they're running out of ideas...
