A leaked document may have the answer.

If this indistinct and blurry picture is any indication, the upcoming Wii U installment of the popular fighting game will be called Super Smash Bros. Universe. In the logo, note that the "U" in "Universe" matches the "U" in the "Wii U" logo.

That cutesy cross-promotional logo vibe has Nintendo written all over it, so we're betting this is legit. World record attempt makers had best plan on a Wii U purchase.
