May 2015: Will Mario Kart 8 outsell Double Dash and Mario Kart 64?

[Ryng]

MK8 AR is around 55%. Assuming what can be the Wii U sales:

15,000,000: 8.25m (above MK DD)
16,000,000: 8.8m
17,000,000: 9.35m
18,000,000: 9.9m (Above MK 64)
19,000,000: 10.45m
20,000,000: 11m

Maybe less, maybe more, of course...
