Iwata Teases Second Triforce in Zelda: A Link Between Worlds

During Nintendo Direct today company president Satoru Iwata described new details the world transferring mechanics in A Link Between Worlds.

Iwata started by teasing an interesting tidbit about the game's logo.  A Link Between Worlds has a shadow of a Triforce that mirrors the iconic golden Triforce, to which Iwata teased - "it would suggest the existence of another Triforce in another world."

The latest footage from A Link Between Worlds also shows how Link shifts between the main overworld and the alternative/dark world - by using mystical cracks in-between walls and the "merge" mechanic to slip through.

A Link Between Worlds also takes far in the future from A Link to the Past - the same world, but an entirely new Link.

What are your thoughts on a potential second Triforce and the alternative world?
