Nintendo has announced a new system, that would feature a different controller, possibly with gyroscope/infared motion sensing controls,
but what is still not confirmed is a dualtouchscreen that changes its buttons depending on the game and still unconfirmed is the abillity to temporarally store some games onto the controller.
...with 8GB on board flash memory for saving photos, files, and games
I'm hoping for L/R triggers, and a Slide pad as well as two actual buttons, resembling a SNES, controller with L/R triggers and a Touchscreen...
