It seems the new 2D Zelda will also feature the new gameplay elements in BotW/TotK. It was clear but now it's basically confirmed. However, I still didn't see any "shrines", so I'm having hopes... Developing 120 or even 153 mini dungeons, which are so extremely repetitive in design except puzzles, are the biggest mistakes of the new Zelda formular.
We will have at least 5 dungeons
the Deku's are back, I’m so happy
I missed them somehow
and we have River and Sea Zoras in the game
