The CaS slot looks to have ordered the characters in a 4x4 layout, looking at the scrollbar's length seems to indicate that it may have 1 more row of characters created, leading to having a total of 20 CaC styles.
The only characters that are NOT in the screenshot above are Groh, Geralt, Azwel, and Zasalamel, and those may be the styles for CaC, unless Azwel isn't one of them
Now onto the leaked character select
If CaC really does have 20 styles, then the remaining 4 slots are probably characters that cannot be used as CaC styles, unless the 2 slots are for DLC, I highly doubt that would be the case however, since Tira is playable day one, I don't think that DLC 3 (being the first post-launch DLC character) would take a slot in the CSS, as they would probably have to be manually added to the character select (kinda like Tekken 7 Season 1)
Also they don't have to reveal every character before release, SC5 did not reveal Alpha Patrokalos, Phyrra Omega, and Elisyum before the game released.
Inferno would probably not be revealed before the game has released, so if TGS reveals Raphael + 1 other character, then 3 would be remained unrevealed until the game releases probably.
