Amazon Canada has posted box arts for three Wii U titles from Ubisoft.
Shown above are Assassin’s Creed III, Just Dance 4, and Marvel’s The Avengers: Battle for Earth. The branding on each is a simple “Wii U” logo on top of a blue gradient and a (not very fashionable) curved yellow border.
Could these be official Wii U box art? We’ll mail Nintendo for comment.
