Eiji Aonuma was interviewed by Kotaku and on this occasion, he talked about the next two projects related to the Zelda series, namely The Legend of Zelda Breath of the Wild 2 (working title) and the remake of The Legend of Zelda Link’s Awakening.
As for the sequel to Breath of the Wild, at the moment the release seems to be set for 2021 but Aonuma has not been too unbalanced on this aspect, reiterating that ” every episode of Zelda needs a lot of work and we want to be sure that everything be perfect before publishing the game. “The team, the game’s producer tells us, has decided to create a new adventure after giving birth to a lot of ideas for The Legend of Zelda Breath of the Wild DLCs , which have just been used as a starting point for what will be a real direct follow-up .
Speaking instead of The Legend of Zelda Link’s Awakening, we discover that the remake was born from the need to make (re) discover one of the best games in the series, penalized perhaps by being released in a period (1993) not particularly favorable for games of this kind on portable consoles. The game is developed by Grezzo, a Japanese team that has taken care of the portals of The Legend of Zelda Ocarina of Time and Majora’s Mask for Nintendo 3DS.
Oh also, didn't squeeze this into the interview but I'm not sure if it's public info – Aonuma told me that his team is on BOTW2 and that Link's Awakening is actually developed by Grezzo (which handled the Ocarina of Time and Majora's Mask 3DS remakes)
