All Mario Kart Shipments! Mario Kart 7+8 Doing Extremely Well, Predict Their Lifetime!

MK8 will surely pass Double Dash at this rate. Might even reach 8m, but it depends on how well the Wii U does in the next few years. And Polygon said it would be the worst selling entry.

I'm gonna guess 13.5m for MK7. Both games have a really good attach ratio.
