The Inq was part of the Game Power panel at CES 2007 and heard some stuff that will be introduced in the next five years of gaming:
The mobile players included the mighty Texas instrument, ARM and a company called Rapport which does the multi-core stuff called Kilocore we mentioned here. All of these guys talked about the future of gaming.
The desktop lads think that the future brings bigger resolutions, more anti-aliasing and ultimately Ray tracing. Ray Tracing is something that graphic cards still cannot touch as it needs more processing power than even the G80 or R600 can provide. The problem will be solved with faster and smarter chips.
The resolution could go up to 3840x2160 if not even higher and the corresponding games will need better content, wiser artificial intelligence and good atmosphere.
