So after the Direct I've gotten a bit of a conspiracy theory on the roster banner on the main website (No its not Mr. Saturn). When I saw them added to the banner I thought to myself "were those gaps there originally?". Well I think they were added in but looking at it now and with much overthinking I'm seeing some interesting quirks there.
1. Most characters are either facing the camera or is interacting/imitating with one or more characters. Dark Pit and Falco, Mewtwo and Lucas, DK and Kirby, etc. Some characters are doing both like Little Mac and Ike have the same pose and King K. Rool and Bowser have similar poses.
2. Nearly every character is either overlapping or being overlapping one or multiple characters or they are way in the background (Luigi, Diddy Kong, Mii Gunner).
With that in mind I notice some exceptions.
1. Dark Samus is rather open. With only a little bit of her arm covered by Shulk she is pretty open compared to the rest of the cast.
2. Another gap is Mr. Game and Watch. As he doesn't cover anybody and there is large gap behind him.
3. Daisy looks like she's striking a pose at someone but its not clear who. Possibly Simon but its not really clear.
I'm not sure it means anything and I'm probably overthinking it. If anything I feel like there will be at least 3 new characters added. You could possibly speculate size of these potential character if its true.
With the way newcomers have been showcased last time, giving us 5 total newcomers in one Direct, I think there's far more coming than 3 newcomers. Especially with Echoes considered.
I do notice however that this time, a lot of characters got "promoted" from their last appearance.
Ridley - Used to be a boss fight only, and a major obstacle in Pyrosphere
Daisy - Used to be Peach's alt ever since Melee
Chrom - Downright confirmed when Robin and Lucina where shown first, and part of Robin's Final Smash
Dark Samus - Assist Trophy in Smash 4, much like Little Mac was one in Brawl, first ever promotion from AT character ever since Mac.
King K.Rool - Used to have a DLC Mii Costume based on him
Inkling - Same as King K.Rool
That's ironically EVERY newcomer outside of the Belmonts.
Pretty crazy.
