Not certain, but investigating what's possible. Lots going on right now, but we're looking in to Switch just in general.— Klei (@klei) January 10, 2018
Klei brought Don't Starve over to the Wii U, and now it seems like the team might be interested in doing the same for Switch. No official confirmation on a port, but as you can see from the tweet above, it's at least being considered. It seems Switch support from Klei in general is being decided on right now.
