A poster on respected forum NeoGAF has claimed that some German stores are selling copies of Mario Kart Wii early, and has posted a photo to prove it.
It would appear that the game comes packaged in an oversized cardboard box in order to accommodate the Wii Wheel, so you'd best make some extra room available on your shelf.
The poster has also shown images of some new additions to the roster of drivers. Click the source link below if you want to see them - we won't post them up because it may spoil things for those who don't want their Mario Kart experience to be ruined.
And we wouldn't want that, obviously.
