Wayforward is one of the first things that comes to mind, except instead of Crazy Galaxy I would like to see how they handle Daisy in her own game since I believe that Daisy's personality and design meshes well with the type of characters that Wayforward tend to come up with. (EDIT: And more voice acting from Deanna Mustard is a huge plus)
Game Freak did do a couple of Mario-related games: Yoshi (or Mario & Yoshi) and Mario & Wario. So perhaps they could do a smaller scale Mario game in the same vein as the two games, probably focusing on a different Mario character this time.
After the debacle surrounding Crash Team Racing, with what, Activision/Beenox establishing an environment for microtransactions (creating a highly grindy economy that gives out little money and most rewards are behind an online-only shop with inflated prices), adding microtransactions to a game well after the reviews have settled to try to "fix" the grind they promoted, I will prefer if Activision steered very clear from the Mario property. They can publish good games, but this relies on Activision not being Activision and that's going to be hard to do since the Mario brand is profitable and Activision can and will use that brand for exploitation.
I imagine that post is facetious given the very rocky road of Fallout 76 lumped with incompetence, but if we do get some nice Elder Scrolls/Doom/Rage related Mario game, you know, if Bethesda remained a publisher and not a developer, I'll be extremely up for that.
Not sure what they will do with the Mario source material. I do want Mario guest starring in a Sonic All-Stars Racing game, which would be probably the only worthwhile Mario/Sonic mashup that exists, hasn't been done yet, and is feasible so far, but that's not a Mario game per se.
If they can somehow make my dream years ago of Mario riding on Air Ride machines in a big city come true, just end my life, it's complete. But having Mario be a partner with a permanent ability and can jump mulitple times, that sounds really good too. Anyhow, this has to be a crossover game with Kirby, but if HAL can make a unique Mario game that fits their style that'll be nice.
Not familiar with those companies, weirdly enough, except for Playtonic of Yooka-Laylee (though I don't really want Playtonic, they don't have my benefit of doubt after that fallout). Believe they're indie studios. Just going to make a general statement that, yeah, Nintendo really should be getting more indie studios on board. They were pretty successful with the Cadence of Hyrule, just imagine how many more games with Nintendo IPs they can trot out through indie developers.
Sure, we can have a sequel to Mario & Wario. I'll be up for making Wario the bad guy again, and Wanda (and her since-then acquired husband) can make her epic comeback.
