Bowser Jr./The Koopalings are major staples in the franchise, so I would honestly say they will stay. Many people also like them.

Rosalina is probably going to stay, mainly because she is a fan favourite and the success of the Galaxy franchise. I can also tell that Sakurai and his team put a lot of work into the Character.

Dr.Mario, I honestly see him getting cut.
