Although a Gamecube hard drive could have some uses, I don't think that it would contribute much to the gaming. When you talk about downloadable Zelda content, I get concerned that Nintendo would feel obligated to create some. I'd rather they work on making the next game in the series, rather than continuing on the current game. But, I think it would be interesting to see 'gamer-made' dungeons, etc. even if it would likely be incredibly complicated and having the possibility of viruses.
