While Switch 2 just came out, it is the fastest-selling platform in its first 4 days ever. That bodes well for the "Switch Effect" continuing with software.
DK is no Mario in terms of popularity but is nevertheless iconic. I put the 10-12.5 million range. It helps that it is such an early title in the console's life, preceding juggernauts like 3D Mario, Animal Crossing, 3D Zelda, Smash, Pokemon Gen 10 etc.
I could very well see Bananza as one of the best-selling 3D platformers on Switch 2, only exceeded by the 1 or 2 3D Mario games that will be on Switch 2. I don't even think a new 3D Kirby game would outsell Bananza.
