Listings for three Ubisoft Wii U games on Amazon.ca show a new design at the top of the boxes, which is possibly the design for all Wii U boxarts. Nintendo seems to be going to extremes to ensure Wii U boxes aren't confused for Wii games (though they will be anyway), trading the white and grey bar for a blue and yellow U shape.
You can see the box on the listings for Assassin's Creed 3, Just Dance 4
, and Avengers: Battle for Earth
. So far, it's only visible at Amazon.ca. We're following up with Nintendo to verify that this is the real design, and to make sure Just Dance 4's
neon zebra stripes aren't part of the standard.
