Not even that, the question is if there will ever be more than one or two more "ticks" in the traditional sense. Apparently the sizes of the elements on the chips are roughly the same on Intel's 10nm and some other 7nm. As an example of what people in the field say: if nothing changes, at 5nm, 80% of the transistors would have to be "dark" (unpowered) all the time. EUV, often presented as the new solution in the processes, would also possibly be too expensive under 7nm even if it's still not even introduced.

So the "tweak-tweak" can become the major cycle soon on more levels.
