The list of upcoming factions that was data-mined may be confirmed as out of date, but there is a ton of solid information to be gleaned from what we do
have. Given that this list was found in the startpos.esf (the campaign file), and the naming conventions of the factions, I've organized the list in its entirety in an attempt to make it easier to read and understand and in hopes of sparking discussion to see if I or anyone else has missed any particularly juicy bits of information.
This list was reorganized after using @agnes1969
's post from https://forums.totalwar.com/discussion/178162/dlc-unearthed/p3
to be more user-friendly. Most of what follows, other than the list itself, is my conjecture based on modding Total War titles for the past 15 years. I may have missed one two factions due to human error, but I'm fairly certain I got them all.
Before I begin, let me start by saying what this list can and cannot tell us: firstly, this list contains all factions currently in-game and the major factions planned for future release. Any faction that exists already on the map would not be listed with one of the "dlc" or "exp" headers to tell us if they will be playable in the future because they are already on the map. In other words, this list won't tell us if any already-existing factions or races will become playable. Secondly, the list gets less detailed the further out we get, so we have little to no information on what minor factions may be coming beyond DLC05. Don't take the absence of minor factions like Araby or the Amazons as an absolute indicator that they won't be on the map. This list simply doesn't give us that much information.
it tell us? It can tell us what factions CA planned to add and in roughly what order at some point prior to the game's official launch. Given CA's statements that the list is out of date and that their plans have expanded, my guess is that we will be getting more than what we have listed, so the numbering may end up being off. For example, we may get two DLCs between the Beastmen and Wood Elves, but in all likelihood the rough order will probably be pretty close. We may get more Campaign packs as well, but there's no way to know that beyond the information we have for Beastmen and Wood Elves. So...
PART I - The pre-existing factions:
You'll notice suffixes at the end of some faction names. "_qb#" indicates a copy of a faction used in
Quest Battles, not necessarily a faction with
quest battles. Factions that have at least one "_qb#" are not necessarily going to be playable, but it's a pretty good indicator that factions lacking quest battle copies were not planned to be made playable at the time the list was made. The "_rebels", "_separatists", and "_waaagh" suffixes are self-explanatory.
Also note that there are no "DLC##" prefixes for either Chaos or Bretonnia. This is because those factions are already on the map and coded into the game, even though Chaos was the first DLC and Bretonnia will be made playable later.
Have I missed anything else of value here?
Part II is incoming, wherein we look at the first two Race/Campaign DLCs
