I think it is neutral to assume that Kotaku and Edge and other's information is correct for the moment.You know that it's alright to be in a neutral position right?
I'm not hoping for anything I just literally don't know and I'm waiting to find out.
I've read the reasoning why it was easier for Orbis to up the RAM (which Edge called a month before) and why it would be a hurdle to do a similar thing for Durango. (Not that the RAM needs changing, that is fine. It's the GPU that is lacking more comparatively.)
As soon as games are announced I won't give a shit any more, as Baconsammy says "content is king."
But rumored and hypothetical specs are all there is at the moment.
