nah they systems are weak blame the prices of gpu's and the lack of heating solutions for apu's. both of these system's are relatively maxed you will see several new techniques but nothing mind blowing. this gen will be 5 years max.
I disagree with that.
Both consoles feature GPU's that use a new architecture
and with that means developers have to come up with different ways
to harness that performance.
There is already talk of getting more GPU utilization on the Xbox 1 with
the introduction of Direct X12 which means those techniques will translate
to the ps4 and further still the PC.
There will definitely be improvements, I'm certain of it, on top of that everyone benefits.
