You heard it here first. Big leakers are colluding not to talk about this because they want to keep it a surprise. Not developed by Nintendo. Not Wario Land or WarioWare, something new. Screenshot this, I'll be proven right.

Not that I believe you but how would they bring back Wario? Wario was an anti Mario both in design and gameplay. Mario's main series is starting to eat Wario's lunch, there's almost nothing a Wario game can do to be ant Mario.
