The traditional design is not 'dated' or 'archaic', no matter what some people may think; Nintendo has proven they can utilise that basic design in interesting ways - just look at Majora's Mask, for instance, or Link's Awakening, the Oracle duo, and even A Link Between Worlds. They've all had their own spin on it.
Hopefully BotW2, or whatever it ends up being named, improves upon BotW in every single way - and that they return to traditional design afterwards.
