The Witness not currently in the works for Switch, but that could change, says dev

The Witness was a groundbreaking first-person puzzle title, which lead to it grabbing all sorts of awards. Sadly the title never made it over to Wii U, but could it hit Switch? Here's what creator Jonathan Blow had to say.

I wouldn’t say never, but we worked on that game for a long time. We could have done more ports, but I felt like it was a good idea to give the team a break and work on some new things. We’re working on new projects now. We’re not really working on ports of The Witness, but that could change. Something could happen. We could outsource it and quality control in-house. But we’re not currently doing anything.
