Calling it now. NX won't get a new Smash but a remaster of Smash 4. With characters that were impossible due to the 3DS' limitations.

1- Ice Climbers
2- Dixie + Kiddy
3- Pokemon Trainer (Gold) - (Meganium, Croconaw, Cyndaquil)
4- Inklings (With transformations)
5- King K. Rool

Much like MK where they now include none Mario IP, I wish they'd go back to using ONLY Nintendo characters in SSB. That's what sold the game when it came out.

1 - Bomberman
2 - Inklings
3 - Shovel Knight
4 - Shantae
5 - Dixie Kong
6 - Knuckles
7 - Ristar
8 - A Tales of character
9 - King K. Rool
10 - Simon Belmont
