Don't expect power consumption on these to come down. Ever.

AMD hasn't even got 20nm products on the roadmap, and consoles would not be first priority for such a shrink.

Well before they can reach 20nm they actually have to release something that uses 22nm which is a regular size and not a half-note.

Actually the names of nodes have nothing to do with the size of anything, and in terms of rough tech equivalence, 20nm IS 22nm. Half nodes no longer exist. Also Intel 22nm is superior to TSMC and GF 20nm because it's non-planar.

And then the interesting thing is going to be that TSMC 16nm and GF 14nmXM will not actually be much smaller than 20nm, but cost a lot more.

Not to mention Samsung advertises it's "nodes" wierdly.
I.E. It advertised it's new "10nm class technology" which puts it anywhere from 10nm to 19nm. (That's for NAND.)

You are indeed wrong on the part that half-nodes no longer exist though.
Half nodes are those that are not defined by the ITRS or "International Technology Roadmap for Semiconductors""

For instance, 65nm, 45nm, 32nm, 22nm, 16nm and 11nm are classed as full nodes as specified by the ITRS.
Half nodes are 55nm, 40nm, 28nm, 20nm, 14nm and 10nm.

In general CPU's from the likes of Intel are always on a full node, sometimes the chipset or other chips may be on a half-node like in the case of AMD's 780 and 880 chipsets .
Traditionally SOC's from the likes of ARM, and in some cases... AMD APU's as well as GPU's are usually on what is called the "half node".
Intel historically used to keep it's chipsets on a node or two behind it's latest fabrication process in order to give the old fabs something to do as an idle fab is wasted money.

Right now the consoles are using 28nm or a "half node" eventually they will move to "20nm" in the next stepping, that probably likely won't happen untill 2015 however because of yield and power characteristics.
nVidia and AMD will likely sample it first and take the hit on their high-end GPU's untill the kinks are worked out.

And everyone knows Intel is the masters at playing the game of fabs. :)
They won't be beaten on that front any time soon, it's literally the only thing that's allowing Atom to go up against ARM.
