I see a lot of people assuming that this takes place 100 years after OOT but where is that confirmed? All we know is that there was some sort of battle at some recent juncture, Ganon was sealed in a castle, and Link has been asleep for 100 years, right?
Mostly based on comments from Aonuma.

At a group Q&A with reporters on Sunday, Zelda producer Eiji Aonuma was asked where the game fit into the franchise timeline. Aonuma said he didnt want to say much about the story at the moment but said hed stare a hint. He noted that that the t-shirt he was wearing showed the symbol for the Sheikah stones and that it was the same one from The Legend of Zelda Ocarina of Time. (In Breath of the Wild, the reawakened Link uses a high-tech item called the Sheikah slate). Aonuma also reminded people that, at the start of this game, Link is told hes been asleep for 100 years. He teased: You can decide what this means.
