I'll go with:

The Legend of Zelda: The End of Worlds

Anything but *U* cant stand when people write metroid U mario U it looks stupid.

Impossible. Almost every game has been named after an item or person within the game that no one knew about beforehand. The Ocarina of Time did not exist before Ocarina of Time was made, the Wind Waker, the Minish Cap, the Phantom Hourglass, the Spirit Tracks, etc. There were no "Oracles" in the series until Oracle of Ages & Seasons. There was no Twilight Realm nor a Princess thereof until Twilight Princess. Skyward Sword as a phrase doesn't even make sense unless you know what the concept for the game is.

The only exceptions are Adventure of Link, A Link to the Past, Link's Awakening, and Link Between Worlds, and still you'd be hard-pressed to guess any of those ahead of time. But your best bet is to aim for something with "Link" in it, because it most likely will not contain any proper nouns that don't exist yet.

Yeah, but we didn't name the system.  Take it up with Nintendo.

The Legend of Zelda: Ocarina of time 2 (this in the first trailer).
But later on the name will be changed to The Legend of Zelda: The Hero of Time
