Nintendo has revealed that it will be broadcasting a Treehouse Live event on Friday 10th July (that's today!) which will include gameplay footage of Paper Mario: The Origami King. You can watch it live right here.
The event will also give us the first reveal of "a title in a franchise new to developer WayForward," which is perhaps a more exciting prospect for many people than the Paper Mario footage. Before you get too excited, though, Nintendo has confirmed that the game is a third-party property, and not a Nintendo franchise.
Treehouse Live July 2020 kicks off at 10 am PT / 5 pm GMT.
