Nintendo Revolution to Play All Previous Games

Nintendo has announced that their new machine, the Nintendo Revolution, due next year will allow you to play all previously released Nintendo games. They did not announce whether this would be free or for a fee (we all know which way that's going to go). The better question is will it be a per title or all you can eat payment system. It would sure cut down on people seeking homebrew emulators if they could pay $15/month and play every NES, SNES, Gameboy, GBA, N64 game whenever they wanted. Gamecube discs will also play in the new machine as well. I'm skeptical how they will compare to the other two giants in this battle. As it's shaping up, the gamer will be the winner (maybe along with the credit card companies! Who can only pick ONE system???)
