Magical Changing Picture for the Page Get
And I kinda compiled my guess for the final roadster, though it's kinda non-specific.
1. Mario
2. Link
3. Pikachu
4. Kirby (Final Smash: Ultra Sword)
5. Donkey Kong
6. Samus (Final Smash: Zero Laser)
7. Fox
8. Yoshi
9. Luigi (Final Smash: Poltergust 5000)
10. Peach
11. Bowser
12. Zelda
13. Sheik
14. Marth
15. Charizard (Final Smash: Mega Charizard X)
16. King Dedede
17. Diddy Kong
18. Zero Suit Samus
19. Ike
20. Pit (Final Smash: The 3 Sacred Treasures)
21. Olimar
22. Toon Link
23. Lucario (Final Smash: Mega Lucario)
24. Sonic
25. Villager (Final Smash: Dream Home)
26. Wii Fit Trainer (Final Smash: Wii Fit)
27. Mega Man (Final Smash: All Star Finale)
28. Rosalina (Final Smash: Power Star)
29. Little Mac (Final Smash: Giga Mac)
30. Greninja (Final Smash: Shadow Claw?)
Characters confirmed via Whiteboard
31. Meta Knight (Also note that the Halberd is a returning stage)
32. Wario (Also note that Waluigi and Ashley are both marked as Wario Characters)
33. Mr. Game & Watch
Characters confirmed via Series Inclusion
34. Captain Falcon (Samurai Goroh Assist Trophy)
35. Ness or Lucas (Mr. Saturn and Franklin Badge items)
36. Ice Climbers (Polar Bear in Smash Run)
37. A Fire Emblem Awakening Rep (Arena Ferox. Will likely involve Robin or Chrom. However, note that Chrom and Gaius both won the first popularity poll for what characters Japanese gamers want to see in the new Smash Brothers)
Speculation
38. Mii’s (The Stage Find Mii has hinted at this for a long time. Also, Reggie has hinted that he will be included in the game in some way, shape, or form.)
39. An updated Gannondorf (Recall how Sakurai stated that when updating Yoshi, he wanted to keep it under wraps as not to cause too much of a disturbance. This may be the same case.)
40. Kid Icarus Uprising representative (PURE speculation territory. Though if Sakurai doesn’t include another Kid Icarus character I will be surprised at how modest he suddenly is. Also note that Dark Pit and Palutena are two characters who were in the top 20 popularity poll Japanese gamers wanted to see.)
41. A Xeno character, likely Shulk (Baseless Speculation besides Xenoblade’s popularity)
42. A Namco character, likely a Tales character or Pac Man (SFlag Assist Trophy clone included in the game. Lloyd, Luke, or Yuri on the fact the co-director is the director of the Tales of Games, and Pacman on the grounds that it’s Namco’s mascot and Namco is working on the game)
43. The fully evolved form of a Grass Type Starter Pokémon (Speculation. It would complete the Pokémon Elemental Triangle. And because Pokémon Gen 3 is getting a Remake. Sceptile?)
44. Isaac from Golden Sun (This is a stretch as he was simply not shown off during the assist trophy demonstration. )
45. A villain from an already established series in the game. (King K Rool and or Hades. Note that Ridley has been confirmed as a Stage Boss, but keep in mind Sakurai’s tendency to play with expectations. Also note that Hades has the potential of being the Story Mode final boss if Sakurai gets cheeky)
46. A representative from the Inazuma Eleven series. (Note that one of the characters from that series was in the poll results of the top 20 characters that Japanese gamers want to see)
47. Hatsune Miku (!?!) (Very low chance, but she was in the poll results of the top 20 characters that Japanese gamers want to see. If she does get in it will make her the first 4th party character to ever grace the series.)
Low Priority Characters for Sakurai’s Team that therefore might not be returning or added:
• Lucas or Ness depending on which one isn’t added first (they are clones of one another)
• Jigglypuff (Was low priority in Brawl)
• Falco (Clone Character)
• Wolf (Was low priority in Brawl)
• ROB (Has yet to be mentioned at all)
Characters likely not returning:
• Dr. Mario (Note that Dr. Mario did have code pertaining to him in Brawl, however was cut due to time constraints)
• Young Link (Forever replaced by Toon Link)
• Pichu (Note that Pulse and Minim where set to replace Pichu, however was cut due to time constraints)
• Mewtwo (Note that Mewtwo did have code pertaining to him in Brawl, however was cut either due to Time Constraints or his similarity to Lucario)
• Roy (Note that Roy did have code pertaining to him in Brawl, and could actually be added to the opening cutscene via a cheat device. He was likely cut due to time constraits)
• Squirtle (Because Charizard was separated from the Pokemon Trainer, and Greninja took the spot of a Water Type Pokemon in the game, Squirtle will likely be demoted back to a Pokeball or cut all together)
• Ivysaur (Because Charizard was separated from the Pokemon Trainer, Ivysaur is an odd one out amongst the Pokemon not being in his fully evolved form. If he returns, it will be as a Venasaur. However, the counter speculation that Septile might be in the game to accommodate a middle generation representation makes Ivysaur irrelevant.)
• Solid Snake (Kojima had stated he was not aware of Solid Snake being back in the game, and invited Sakurai to add him in again despite not wanting to bring Ground Zeros/The Phantom Pain to the Wii U. However its likely too late to add snake back in and the previously mentioned not bringing Metal Gear to the Wii U makes Snake’s chances almost dead.)
