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 didn’t want to say much about the story at the moment but said he’d 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 he’s been asleep for 100 years. “He teased: “You can decide what this means.”
The Sheikah symbol has been in many games, so to specify OoT and the also mention Link has been asleep for 100 years as a hint when asked where in the timeline the game takes place seems like a strong indication that it's 100 years after OoT. The Hero of Time is famous for sleeping 7 years and getting defeated by Ganon in the Fallen Hero timeline would be good reason for his 100 year nap.
Thanks for the source. I do think it's likely that Breath of the Wild takes place 100 years after Ocarina of Time in the Fallen Hero timeline. Granted it's possible that Aonuma name dropped Ocarina of Time because it was the first game to feature the Shiekah Symbol.
