For me, definitely Nihon Falcom first and foremost. They've been on top of their game and I trust that their action and turn-based RPGs alike will be great in the years to come. I also have faith in Toby Fox that DELTARUNE will be a beautiful whole once it's done, but that's probably many years off.

Notably, I'm not really trusting of Atlus, Squenix or ZUN in the same way. Atlus' priorities aren't in the right place, and while Persona 5 was a super fun game, it was still centered more around being appealing than being the best it can be which isn't very confidence-inspiring. Squenix hasn't made a game I loved since FF XII. And ZUN just has his ups and downs a lot and Touhou 16 was pretty forgettable. Blizzard has also lost me, they had their good years and now they're over. Key as well hasn't made a great game since Little Busters (Rewrite was great but they were more the publisher of that than the developer).

I'm kinda torn on 07th Expansion. I'm sure Ciconia no Naku Koro ni will be great, but Ryukishi's works tend to be only explicitly good when they're long epics. If he comes out with shorts I'm not gonna be looking to play them by any means. Long stories though? Hell yes.
