They should've held it back, added sixteen more tracks, and called it Mario Kart 8^2 (pronounced: "Mario Kart 8 squared")
Still a missed opportunity in my eyes.
Then again, the Switch does need more games...and Mario Kart 8 is good enough as is.

The game has 48 tracks.

How would adding 16 more make it squared?
