Have you heard rumors about new video games console from Nintendo? Project Café. I think that it;s designed for me, because of my coffee addiction ;) Anyway from Wikipedia and other sources it should handle HD resolution (finally!) and controller with built-in screen. It should be a little more powerful than Playstation 3 and Xbox360.
About internals: rumors says that it should be powered by custom made IBM processor with three cores, GPU should be from ATI (R700 family) and 512MB of RAM. Doesn't sounds futuristic, because PS3 and X360 tend to be outdated soon.
The biggest evolution seems to be a controller. Gamecube (<3) based with 2 analog sticks and before mentioned LCD screen.
I wonder how it will look like and what games will serve to us. Are you waiting for new console?
