WayForward has confirmed a new Shantae title! Shantae 5 is in development for the Switch right now, and WayForward says it'll release later this year. The announcement came from Apple's Apple TV+ announcement earlier today, and their games trailer featured the tiniest snippet of gameplay. We can't even be sure it's from Shantae 5 at this point!
That's honestly all the info we have for right now, but that's all I need to get excited!
