Its getting harder and harder to impress the audience with better graphics. And with the limitations of the available ram and the high bar set for graphics eating up all available cpu/gpu time it's hard to try any new game play innovation.
Plus the huge 2nd hand market available by now for the current gen consoles and people starting to get lured more and more to pc where you can get games for under $10 that perform and look better I can see why they want new consoles.
