Given the fact these may well be placeholder images, don't read too much into them, but just in case they're the real deal, what do you think of the splash? And the colour scheme?

The yellow is a bit weird, but the "swoosh" design is something we've seen from Nintendo plenty of times before, from the spine of DS games to the top of GameCube covers.

We're asking Nintendo for clarification, and will update if we hear back.

UPDATE - Target now has images of the same art, this time showing the game's spine as well.
