You are confusing datamined code references being added or removed with characters actually being developed for the game. Datamining references being removed doesn't tell you anything, and them being added only tells you "this character is at some stage of development".
For example, Rogue and Gambit were datamined as the Season 5 additions some time ago, complete with voicelines from existing characters referencing them, and the new Season 4 gallery cards have a very direct, if not outright blatant hint that they are indeed the next heroes added, yet in the current game code patched today for the Season 4 start, their IDs were among the references removed, while others were added. What does this mean? Fuck all. We aren't privy to the development of this game, we have no idea why a character reference is added or removed from code in a patch.
There are other indicators for a character being an imminent release, as we got for Phoenix, Blade, Daredevil, Angela and have for Rogue and Gambit.
