I gotta say that, given the way ARMS characters fight, in comparison to Rayman, they really would make sense being in a single trailer. Of course, that's just wishful thinking (I don't expect it to happen at all lol), but it'd be cool to see something that's basically "Look how much we can stretch our arms!" followed by "Arms? Who needs those?"
I honestly believe that is the case to be Legit Reveal simply Because of:
A. Sakurai was supposed to Go meet with the Owners of the Next DLC Addition who looks to be a Western Character based on his Explanation.
B. The Ubisoft Mii Costumes are clear indicators that Nintendo and Ubisoft looks to have Talked recently for their own Character Series Reps to be in but no Rayman content with them.
C. As blatantly Similar of a Concept of Both Rayman and The Arms Characters are it’s not Secret that All Characters ever created in Super Smash Bros are a carbon copy of each other, even so going from:
- Luigi is a Clone of Mario in Super Smash Bros 64
- Ganondorf is a Clone of Captain Falcon as Moveset design mechanics in Super Smash Bros Melee
- Young Link, Toon Link & OG Link are Clones of each other in Melee & Brawl
- Pichu is unquestionably a Clone of Pikachu in Melee
- Dr. Mario a Clone of Mario in Melee, 4 & Ultimate
- Echoes are the definition of Copy and Paste More Characters, hell even both Belmont’s were revealed simultaneously
- Joker’s mechanics comes from Pirahna Plant who both are DLC Characters and got revealed back to back prior to the Release of Ultimate are the Best examples of one made after another which can (and more likely) be the Same for Arms being the Mechanics for Rayman
