Since the prototype introduction on Computex 2012 (i think) theres not more info released. I remember they talking about 11.6" , 13" and maybe a 14" versions , a HDD on the keyboard also and the possibility of a dedicated GPU on the keyboard .

But since then theres no more info and with the release of windows 8 so close and everyone detailing final specs ; maybe they are still trying to get the "concept" fully ready , anyone had heard anything ?
