They will probably keep this formula but will probably make a very different game next time. Very different location, dungeon scheme, themes, etc. Maybe this time Link will be able to travel to the future? I mean, not our future, but Hyrule's/Termina's/Wherever's future. Maybe a world dominated by sheikah/hylian tech, kinda like a distopia, mixing elements from future and past. I mean, they've been experimenting with advanced technology on Zelda for quite a while. The first 3D game I remember having these elements was Twilight Princess, which features cannons, motion controlled statues and a freaking city in the sky! Then Skyward came with Robots and stuff, and now we even have automated creatures (even automated "divinities") shooting lasers and stuff! So... it would actually be cool to have a game partially set in the "future" next time. 
Bet with Teeqoz for 2 weeks of avatar and sig control that Super Mario Odyssey would ship more than 7m on its first 2 months. The game shipped 9.07m, so I won
