Well, who knows what the future will bring?
I personally dream of a single processing chip powerful enough to do all the standard CPU tasks, but also acting as a GPU. Super powerful so games can be super compressed, use procedural textures, etc, with ease.
I also dream of a single memory unit which is super fast, and super big - so it can act as memory and storage at the same time.
Two models - one with a optical drive, and one without. Entire game catalogue downloadable, do discs aren't necessary, but it you live in a shitty connection area, or whatever, you can still play the games. All games run straight off the memory unit, though.
