EDIT: Here's the actual, really for real box art:
Also, IGN just posted new hands on impressions from Leipzig:
Apparently they're showing the same levels that were shown at previous demonstrations, but there was a secret code you could enter that unlocked two as yet unrevealed levels: Beach Bowl Galaxy and Cookie Factory Galaxy.
Fearing for our lives, we jumped into Cookie Factory as fast as we could, hoping Nintendo's PR handlers hadn't noticed. As you might expect, the level is made up of platforming over different types of chocolate, caramel, and mint. This was some of the most classic platforming we've seen in Galaxy, yet. A trail led us through a tunnel where the ground was constantly moving and we had to proceed while maneuvering gaps and electric buzzers. Eventually we made it out into the open where a series of large cakes hovered in air. We made our way over the trail of desserts towards a large cake at the end -- but that was when a Nintendo representative came over and reset the Wii. We were warned that we would be removed from the press lounge if we were caught playing the "secret sixth level" again.
