You take the Hyrule and I'll take the Lorule. Link, however, can take both in The Legend Of Zelda: A Link Between Worlds, which allows our hero to shift between the two alternate dimensions during the course of the adventure.
You can see both worlds courtesy of a lengthy new gameplay trailer, alongside some of the new mechanics and Link's new nemesis. The Legend Of Zelda: A Link Between Worlds releases on 3DS (and 2DS) on November 22nd. Hands-on preview here.
