A claim which is also an absolute!
That line always makes me think of this:
Normally I would be confident that Dixie is staying in Mario Kart now, except we've seen Nintendo make.......stupid ideas with their Kart rosters, removing popular fan favorite characters from game to game like Diddy or Waluigi but adding Honey Bee or 23 Seconds into the Future Mario, who is Mario just 23 seconds into the future from present Mario. So while I'm happy Dixie is added, I fear Nintendo will just be one and done and move onto someone else when Mario Kart 9 comes out in 12 years.
With the large cast of characters from multiple universes that they can use, there is no reason to use generic mooks or 37 Mario Peaches. Use Dixie, use K Rool, use characters on hiatus so they don't get forgotten.
