User blog comment:Smasher51/Corrin and Bayonetta Are Not The Last DLC Characters...?/@comment-11932647-20160119014356

Knowing Sakurai is a big troll, you may be right. My guess is we may get 3-5 more DLC characters, and my guesses include (not all of these are ones I want) King K. Rool, Wolf, Shovel Knight, Snake, Banjo, and Isaac.
