Since it uses a MicroUSB port for power, I think that theoretically it could be plugged into a computer to get firmware upgrades. It's plausible anyways, if only just as insurance to make sure Nintendo doesn't have to recall them just because there's a change or glitch in the HDMI spec or a bug they missed in one of the roms. And if that's the case... Maybe we can jailbreak it and add more roms? It's a very slim chance, but I think it's possible. Perhaps it disables the data channels by default, but you can press a secret button combination to access a utility mode?
