Where do you think the title known as Zelda Wii-U be set? Will it be a place we've seen before (Hyrule, Termina, etc....) or a new land entirely?
If it will take place in a land we've seen before, I would expect it to be in Hyrule, because the other places are meant to be unique to their games. A new land might work, but that depends on how Link ends up there.
Do you want the game to be a sequel to a current Zelda game?
I think the best way to answer this question would be to look at the various threads:
• The Legend of Zelda / The Adventure of Link: As the most classic games in the series, I do think that it's high time we see a continuation, although I'm not sure how that would work from a gameplay perspective because it's been so long. I think that Nintendo should stay away from advancing the Downfall timeline for now, especially because it has the most installments on the timeline.
• A Link to the Past / Oracle series / Link's Awakening: I actually think a prequel and a sequel would work best with this. There needs to be a game that will actually depict the Imprisoning War, so Link's defeat in Ocarina of Time becomes more than "What If?" scenario. A sequel would also help bridged the gap between this thread and the classic one, and while it's apparently meant to be a time of peace, I think there's story potential there. However, thanks to the GBA port of A Link to the Past, this entire plot thread can be played on a GBA, so I think it should stay as a portable subseries, so I would expect the sequel to be on the 3DS or whatever the next handheld is. The prequel, however, should definitely be on a console. I know asking for two more games contradicts that I just said about the classic games, but I think I can make an exception because it would just be adding more games to the Downfall timeline rather than actually going forward.
• Ocarina of Time / Majora's Mask: I maintain that any continuation to the Hero of Time's story should be on the 3DS, and as such should wait until Majora's Mask 3D becomes a reality.
• The Wind Waker / Phantom Hourglass / Spirit Tracks: I think Spirit Tracks ended pretty conclusively, but there should be a sort of interquel set between Phantom Hourglass and Spirit Tracks, and I think it would work pretty well for the Wii U, so that we have some sort of compromise between the gameplay of Wind Waker and Phantom Hourglass.
• The Minish Cap / Four Swords / Four Swords Adventures: Four Swords Adventures ended this story on the Child timeline, but it's possible for it to continue on the Adult or Downfall timelines. However, since I haven't played Four Swords Adventures, I'm not sure if this is a story thread I would prefer to see on the Wii U or the 3DS.
• Twilight Princess: Nicole suggested a sort of spiritual successor to this game, and since Twilight Princess was the "premiere" Zelda experience for the Wii despite being a port, so having a full-fledged game meant for the system set in that timeline would be fantastic.
• Skyward Sword: I haven't beaten this game or Minish Cap yet, but I'd like to see a game set between the two, if only because I want Ganondorf to have chronologically made an appearance in a game before Vaati, and Demise doesn't count. As such, this wouldn't necessarily be a sequel to Skyward Sword, but certainly set after it, and I think "the original Ganondorf" is a big enough plot thread to be worth of putting on the Wii U.
As such, my answers are:
• Ocarina of Time / A Link to the Past interquel
• Phantom Hourglass / Spirit Tracks interquel
• Twilight Princess spiritual sequel
• Skyward Sword / Minish Cap interquel
Do you want any locations to come back from any Zelda Games in particular? (I want the Lost Woods to come back, I loved that location in OoT)
I have no preference, but I had to choose, I'd say Death Mountain.
Should the world be larger, smaller, more dense, less dense, or the same as Skyward Sword's overworld?
I actually liked Skyward Sword's overworld, but perhaps they would implement the "dual worlds" aspect of A Link to the Past and Ocarina of Time. The surface should definitely have more connections to each other, and there should be more simpler warps than constantly having to fly around to get from place to place. It should be large, but not quite as big as Wind Waker's overworld, and it should be easy to travel across, with the addition of warps.
