Tech-wise, yes. Explaining your customers why their 1-2 year old "high-end / monster"-advertized SKU is already outdated, not so much.
I think it is the name that people still associate a certain power with, still.
The consoles will be pc now forever so whatever Sony or MS offer will also be available to a pc gamer, most likely even before the consoles release and better hardware will also be available because of obvious reasons.
The console competition is a snail race now from a technical point of view, in my opinion and the only difference with Sony and MS is that their cycle when to release a new system is not aligned anymore.
