One of those Twitter leakers says Nintendo will announce new hardware soon, and that it will be something unexpected.
I mean, everyone's probably expecting them to do something to distract from the PS5 and Xbox Series X launches. Most people are probably expecting a new Switch model though. I would be pleasantly surprised if it really were something unexpected.
Edit: I'll include a link, even though it's slightly NSFW. I'll make it code so it doesn't embed.
Edit 2: You know, the more I think about it, this announcement would probably be more "Game Gear Mini" in scale than "Nintendo 4K". I can dream though, right?
Perhaps a Switch "home" version. Aka docked type only
