Could it be that game companies went through some growing pains developing for the newer consoles? Maybe they've learned their lessons.
Sony's box is essentially a dedicated linux box, and MS's box is partly a PC and will soon essentially be a PC... these are not 'new unknown' platforms that should have huge growing pains. These are plain-jane x86 boxes with pretty 'normal' hardware (especially compared to previous generations of consoles).
The issue is that both companies released hardware that was too anemic to live up to expectations, and programmers are desperately trying to find shortcuts and cheats that work at lowering quality just enough that people will not complain, but sill offer a 900p/60fps/2xAA experience that will pass as OK for the next few years. The issue is that in a little over a year (my guess is summer 2016) we will have mobile tablets with better graphics capabilities than either console. If either company is serious about providing a console experience than we will see a half-cycle refresh with better GPUs that are much more easily capable of 1080p/60fps/4xAA/AF to run out the rest of the console generation.
Hopefully next gen they will not be so silly hoping that 'the cloud' will save them and we will see affordable 4K consoles come out in another 6-7 years.
