Will Mario Kart 8 (Wii U + NS) outsell Mario Kart Wii?

As of today this is the longest we've ever gone without a new Mario Kart title.

Mario Kart 8 Deluxe to Today = 1651 days (April 28th 2017 to 4th November 2021)
Mario Kart 64 to Mario Kart Super Circuit = 1650 days (14th December 1996 to 21st June 2001)

If you don't class Deluxe as it's just an upgrade of 8 then well... Mario Kart 8 to Today = 2716 days (29th May 2014 to 4th November 2021)

Mario Kart 9 is well overdue.

Mario Kart 8 will keep selling until 9 comes out.

My first gut reaction was that this can't be true given that the switch isn't even 5 years yet. Then I realized that we don't have 2 hardware skews anymore and it suddenly made more sense.
