Yeah dude, I've always felt good things could come from a future-ish Zelda. As long it's not so far forward from the current Zeldas that it breaks the whole system (hurr durr go forward in time, buy gun, go back in time kill ganon easily), it could be fantastic, especially with the potential for so many new, yet appropriate, art styles. I'd be all over a steampunk-ish Zelda. For the record I don't strictly feel guns would be a bad thing, as long as they did it right. e.g. some of the very first, super-primitive firearms could be appropriate.
Imagine a zelda with multiple time-points (more than Ages) where there are multiple timelines and you have to pretty much fix each time in the correct order to get back to the true timeline, or something along those lines. That kind of concept really interests me, I would like to see time-based storylines step beyond "two timepoints, fix the first to fix the second". Then imagine the potential mind****ery that could go on where you have to **** up certain times further to make it possible to fix **** overall.
