When asked directly by a fan on twitter if there was any chance of Divinity Original Sin coming to Switch, Larian Studios responded by saying that they are focusing on the PC releases of their games right now but once that priority is done they will look at other systems.
We will look into other platforms right after PC has been released. 😉

Obviously this isn’t a confirmation of anything, but it is telling how they answered. Given that some other companies outright rejected their RPGs coming to the Switch, this does make one wonder. Maybe they are looking at bringing their game to the system? We will keep you updated.
