I think that the next Zelda should break some barriers in series, some fantasy tech would be cool, kinda maybe make hyrule like the world in FF6. That would allow for more gameplay options and weapons. The game should not have the MP3 look, but maintain the "pleasent" Zelda look. I think it would be cool if their was like a moon temple, where you needed a gravity suit a certain parts, but it could be turned on and off to let you get to hidden places by floating.
The moon could be really cool unlike in FF4, it could have "alien (different)" vegetation and such : ). I also think they should have a Wind Temple on a huge mountain (usually where there is a fire temple), a mountain 3x the size of any others. The mountain should be filled with endless nooks and crannies and places you just keep finding months later.
Also the Zelda series has not had a jungle really (majora's mask might have more I think about it) that would be new.
I also think they should have exp and lvl, but make it kinda like Diablo 2, where you have to choose a way to build links moves, which would create alot more replay.
