I want to see the return of Kakariko Village the way it was portrayed in OoT: bustling, peaceful, big 'ol windmill, and actually populated unlike that tumbleweed ghost-town of three native residents that was TP!Kakariko. There's just so much about Kakariko that I loved, the windmill and graveyard being some big ones, and it's OoT music being another. If Kakariko itself is not brought back, at least give us a town like it, as long as it has its graveyard; I love that graveyard for some odd reason.
Of course I want to see all the staple locations again too, only improved. I would like to see:
A large, preferably open forest, complete with a Lost Woods;
Death Mountain, hopefully with the hotsprings returned, or scenic lava rivers running down its sides, or both;
Zora's Domain, which I want to be half or completely submerged into an underwater Atlantis styled city since that would be awesome;
A fishing hole as large and beautiful, if not more, than Hena's Fishing Hole, which was gorgeous compared to OoT's.
Snowpeak/Snowhead/something frozen that is not Zora's Domain.
