“28nm is actually the last node of Moore’s Law” is referring to the “Density at minimum cost per transistor” version of Moore’s Law, not the “smallest feature size we can get”.
Yeah, but if the cost per transistor were going up, you’d expect them to stop there. But a little googling turned up this press release talking about 14nm, and this roadmap which extends out to 5nm.

There are applications where smaller sizes make sense, even at higher cost.
