Sadly I don't see anything Wario announced here, but maybe we'll get some interesting third party exclusives instead. Who knows, Wario Land and WarioWare spiritual successors could be revealed for the Switch 1/2, and we could get DLC info for games like Hyrule Warriors: Age of Imprisonment. Heck, maybe if they're smart it'll turn out that Microsoft had Rare work on a new Banjo game or that new Spyro game gets revealed...
Oh that also happens to be Rift of the Necrodancer's 1 year anniversary! I bet they got a great relationship with Nintendo and especially because of Cadence of Hyrule, I wonder if they'll do some sort of update that's different from their usual song packs. It's cool how they collaborated with Pizza Tower too
If Nintendo trusted them with Zelda, and if they also trusted Treasure with Wario World, then I think them trusting a Wario indie certainly is possible!
