So I believe we are less than a week away from Nintendo's long awaited (and overdue) Nintendo switch Direct presentation which will also have a Nintendo tree house even that will go in depth on all stuff shown during the Direct.
I'm hoping for Wario Land 6 or Luigi's Mansion 3, but sadly neither seem too plausible at this point in time. At least not yet.
Other than that, I'm hoping the 3D Mario game really is more like Mario 64, that the Switch has decent third party support, that Breath of the Wild has more to it tha what's seen in the videos so far (like proper dungeons) and that Pokemon Stars is actually a real thing.
