Id assume its a new Mario animated movie, since Universal distributes those. But I could also see it being a Kirby movie, repeating the partnership with Universal/Illumination thats already proven to work.
Cant imagine its a planned sequel to the Zelda movie thats releasing next year, so no to that idea.
Be awesome if it was a Metroid movie. Dont know if that IP would have that much traction tho.
