Mario Kart 8 will be the worst-selling Mario Kart ever. UPDATE: Nope, my prediction was wrong.

I typed "will Mario Kart 8 sell more than Super Circuit?" into the Magic 8-Ball.

I asked the Magic 8 Ball if Mario Kart 8 would outsell Mario Kart Wii; it said no. Then I asked it if Mario Kart 8 would outsell Double Dash!!; it said yes. Seems as though it has sense...!
