Since BotW is launching at the very beginning of the switches lifespan, another 3d zelda is most likely to come out on the switch.
I personally hope they reuse the assets from BotW like they did for oot when making majoras mask. If they do this they would have to make a very different zelda. Since BotW is focusing on the nature of the world maybe the next game could focus on towns and cities?
What are your ideas?
