I own a number of systems including the XBox and Dreamcast. My passion and eye for detail in the games makes the graphical difference between these two systems fairly obvious to me. However, most of my friends and my wife don't see a major difference in the graphics between the better DC games and your typical XBox game. To me, the DC is the first system that, while overshadowed by newer systems, manages to not look archaic even though it's outdated. My question is, what is the next big thing going to be in graphical technology, that is going to make the difference between the next generation of systems and this current generation obvious? Super High Res Textures? Better lighting? Something else? Thoughts?
