I’ve been a Grim Dawn fan for the past 3 years. Originally bought it on GOG around 2020 but only started playing seriously around 2024. Bought it again on Steam last year so I can play on my Steam Deck. It’s been a blast. But so far I noticed SD performance kinda leaves a lot to be desired. I was hoping with Fangs of Asterkarn this would be the definitive version of GD, if you could release a Complete Edition for Nintendo Switch 2 I’d buy it all over again. I can settle for a digital copy but a physical cartridge would be very much preferred.
Welcome to the forum. 
Zantai answered this in a Steam thread a little while ago.
"Not likely.
We don’t have the internal resources or expertise to make a Switch port. Outsourcing is expensive and a gamble (and managing an external team doesn’t exactly sound appealing), and getting your game, especially a game that’s been out for 10 years, noticed on a console is extremely difficult. Nintendo tends to focus on promoting their own first party products."
