There is already a thread about this, sorry... ;-)
Yes, I think probably it is too new. The other thread title says the plug is supposed to be "ready for production", but what I actually read in a link provided there is that the spec is ready, so hardware designers can start designing and then producing plugs according to that spec. So it will take a while until you can buy actual plugs, and actually the mainboard where that plug needs to go has already been designed a month ago or so, they only want to make bugfix changes now if I got that right...
