Remember the thread we had about console generations as defined in wikipedia chronologically vs console generations as in technical advancement? I think that double-entendre is biting back.
What I think the guy is saying is that it is not commercially viable for the foreseeable future to think of complete platform overhauls, because with those come increased development costs for toolchains, retraining etc.
What we might see is updating of generally stable platforms. Think of a PS4 that has the new cell with more SPEs and a better GPU and more memory and a bigger HD and a faster BluRay drive... but it is still backward compatible with PS3 and uses the updated versions of the same devkits. Same for the x720 or whatever its name: its new devkit would use dx10 and dx11.
Then if you want you can sell gyroscopic or IR-based wiimote-like thingies, boards, VR goggles or whatver, but again the core of the platform isn't overhauled every 5 or 6 years.
A "softer" evolution like in PCs, at the end of a day, where nobody talks about generations.
And basically what Nintendo did in the GC>Wii transition, though I have been whipped before for advancing this idea :)
