Suda51: "I'd love to bring Killer7 to Switch. However, Capcom owns 100% of the rights to that game, it's really thanks to them that the PC version came out at all just because they OK'd it and a publisher came along to help distribute it, which is really great. But I'd have to talk to them again to see if it's possible to get the ball rolling on Switch. The thing about Killer 7 is that it really was a sudden release, we weren't able to do much promotion for it before it came out, so I really feel like I have a duty to make sure that people are even aware that it exists."
