i'd like them to go back to the basics and actually make a zelda game that's about adventure. i love the story in zelda games. i am a fanboy of the series that way, but i love the puzzles and exploration more. the first legend of zelda was inspired by miyamoto exploring caves and the woods when he was a kid. it's the only zelda game that's like that. shadow of the colossus had elements that felt more like the first zelda game in 3d than recent titles.
i think they should keep stuff like towns, upgrades, the story, and all that, but make the idea focused more on the adventure of it. i think the zelda team's grown stale. they look at the ds and go, 'how do we make a zelda on this? touch controls.' they look at the wii and go, 'how do we make a zelda on this? motion controls.'
they need to be inspired again. go out and explore, find that spark. or give it to someone who has that spark. the guy who made mario galaxy very clearly wanted to trade off.
