I'm pretty sure that they're going to have a hell of a lot of difficulty getting much smaller than that, there is an actual physical limit to how small they can get it. Once you get to a certain size too many electrons will tunnel across the gaps and the circuit will become useless.
I'm amazed they actually got it down to 28nm, at that scale you'd think the Casimir effect would cause all sorts of trouble.
