Who will Archaon be able to confederate?

In patch 9.0/LotET they're reworking Archaon so he gets to confederate "all chaos factions" and in that stream Skarbrand was used as an example of someone he could confederate despite not being in warriors of chaos. However, they also used the phrase "twenty something"

But if you count up all chaos aligned factions:

WoC (10), Norsca (3), Khorne (3), Nurgle (3), Slaanesh (3), Tzeentch (2), Skaven (7), Chaos Dwarfs (3), Beastmen (4) and Daniel (1) you get 39, which is a bit more than "twenty something"

My guess is it'll be WoC, Norsca, Daniel and the monogods (25 total) although, given that they've forgotten about Daniel since Launch it wouldn't surprise me if they forgot him again for this one. What do you think?
