Well, at least there are two types of game technology advancements: 1. consoles 2. game engines. While we're waiting for the PS3 and the "ZBOX", at least game engines are being improved for the current consoles. I don't know if anyone has heard of it, but a game coming out called HAVEN is supposed to be utilizing a brand-new technology. The website describes it better than I could:
Haven: Call of the King is the story of a young hero's epic journey to free his enslaved people from the clutches of the evil Lord Vetch. Using Traveller's Tales' advanced T-Total gaming engine, which allows a multitude of genres to be seamlessly integrated into one game, Haven: Call of the King features many gameplay styles - platforming, turret-based shooting, boat and land vehicle racing, arena combat and space exploration. Players will travel through lava-filled subterranean mines, then race across oceans in jet-powered speedboats to pilot spaceships for interplanetary dogfights - all without a break in gameplay. Available Winter 2002, Haven: Call of the King is poised to transcend the boundaries of interactive technology.

It's not holographic, but I'm looking forward to being able to explore massive maps without loading interrruptions. When I read about this, I realized that they can still be improving game technology while we wait for more powerful consoles.
