I think characters that are most likely gonna get removed are Dr. Mario, Dark Pit, and Lucina, due to the nature of their existance in Smash Wii U.
I also doubt that Ryu and Cloud will make a return, unless Sakurai (assuming he doesn't stay true to his word) really pushes for them.
"Just for comparison Uncharted 4 was 20x bigger than Splatoon 2. This shows the huge difference between Sony's first-party games and Nintendo's first-party games."
