I haven't really thought through my own scenario, Nintendo developers are paid good money to do it for me, get to it! But, I'd like them to just go wild, really. Do something radical and different, don't just follow the cheat sheet Zelda games typically tend to use. Lots of games are trying new things these days, whether for better or worse, and another game like SS and my interest in the series will just plummet.
So, impress me Nintendo! Is all.
