Hello tlozbj. I have a theory about zelda u and where it could place in the zelda timeline. I think it going to take place as a sequel to Four Swords Adventures in a new era because look how colorful Zelda U looks like in the trailer. When you look at the zelda timeline and look at where four sword adventures is, it's placed in the shadow era of the child timeline. Maybe a new era started when ganondorf was defeated in the game, which means that we might not see ganondorf in Zelda U.
