It's no secret that Mario Kart 7 is due out in December, but it now appears that a certain 3DS-compatible steering wheel from Hori will be too. (Stoked?) According to Andriasang, Amazon's Japanese site listed the peripheral sans photos, pricing it at a cool ¥1,280 (about $17). Not long after that the blog snagged a few press shots of said unit, which looks like a odd blend of the iPhone-oriented Helix grip and Nintendo's own Wii Wheel. The attachment is said to feature tweaked shoulder triggers and Nintendo's Official Seal of Approval, but won't score you extra SlidePad functionality. You'll find a shot of the back past the break and more details at the links below.
