Like others have said before me, it does indeed feel weird and hollow that the Switch doesn't have its own DK game. With K Rool in Smash (and kinda Banjo & Kazooie as well, who are honorary DK characters), the Mario Movie, and almost all the most notable past games being on the Switch (and the ones that aren't, there's a good shot they'll come to it, save for Returns, sadly), it feels like this should be a great time to be a DK fan. But it's all severely hampered by the fact that we don't have an
announcement for a new game. A new game which, mind you, could still be years off. But we don't even have so much as the small teaser of "the next DK game is in development"
Good news is, I do think there's a lot of hope for the future. With there being much more DK content in the Mario movie than I, and probably most DK fans, expected, the foundation is strongly there for a DK film. And, while I hope Nintendo doesn't go full Cinematic Universe because I think the concept is wearing thin, I'm hopeful they'll explore the extended Mario universe with a DK film (as well as Luigi's Mansion). I'm also hopeful that, once Retro finally finishes Metroid Prime 4, they'll be set on making a new DK game. And with more 3D platformers having released to success these past years (Spyro remakes, Crash remakes, Crash sequel), Nintendo's 3D platformers succeeding in open-world (Odyssey, Kirby and the Forgotten Land), and Retro's experience from making Prime 4, there is a lot of hope that we'll get an open-world DK masterpiece. It's just a bummer that it's likely a long time off, and that another development studio wasn't tasked with at least giving us another 2.5D entry if Retro Studios were going to be tied up this long.
