Chibi-Robo. The original game is fantastic. It would be nice to get a new game in that style, along with HD remakes of the first game and the third game (a japan-only release).
Oh, and WarioWare has never died or been dormant for more than 5 or so years. We got WarioWare Gold as late as 2018 on the 3DS. While it was shocking to get a WarioWare that long into the life of a Nintendo platform, it happened. It had a lot of reused minigames, but there were some new ones.
So WarioWare has pretty much always been a pretty active series. It's Wario Land that has been dead for 13 years.
