These are some of the accessories that Nintendo tell us they are
developing to come out with the GameCube:
NINTENDO GAMECUBE Digicard

It includes 4 megabits of flash memory. Nintendo have come up with a
highly efficient device taking into consideration the play environment.
NINTENDO GAMECUBE SD-Digicard Adapter

This adapter is compatible with the stamp-sized, large capacity
recording media, SD Memory Card(64MB) being proposed by Matsushita
Electric Industrial Co.
NINTENDO GAMECUBE Wireless Controller Wavebird and
Wireless Receiver
Has the cord on past consoles always been just that little bit too
short? Do you trip people up when they go to walk past the
Nintendo in your house? If the answer is yes then this is for
you!! You no longer have to worry about the cord!! Even is
someone steps in front of the reciever it will still work cause it is
not infa-red but uses radio waves instead. The transmission
distance is about 10 m at the most, though I expect you would need a
very big screen to be able to see it well from that distance.
NINTENDO GAMECUBE Digital Video Cable

Supports the uniform standardized D Terminal which is compatible with
the advanced digital broadcasting environment. Nintendo plan to sell a
component with three inputs (color coded).
