Nintendo won't talk about who's making Nintendo Labo

Nintendo is being very secretive about one aspect of Nintendo Labo. While obviously Nintendo's own devs are involved, they're not opening up about what teams are handling development. Nintendo has been asked multiple times who is behind the game, and they've declined to comment. At a press event today, Nintendo said they aren't ready to talk about who's making the project just yet. Will Nintendo tell us who's behind the experience before it launches, or will we have to wait for the game's credits to find out?
