There are some rumours floating on the web that Nintendo's Wii console may soon get an external hard drive:
Game Labo, a Japanese magazine, is reporting a rumor that a Nintendo meeting was held recently to discuss the possibility and fate of an external hard drive for the Wii. Of the rumors reported, it was placed on in the “rather reliable” category. If it does indeed happen, I wouldn’t be surprised. Nintendo knows these games take up space, and while they gave us 512MB to be cost effective, they know that won’t be enough for the smaller number of oldskool gamers out there.
