Ones we are pretty sure about

So that leaves us a spot for a mystery codex, which if I were a gambling man I would bet on agents of the imperium. which will be Sisters of battle, sisters of silence, and the various flavors of Inquisition. If they get a kit (and to be fair most codexes have gotten at least one), with those factions it would most likely be Plastic sisters of battle.
I say this as a true sisters of battle skeptic, but it just makes sense to release plastic sisters as part of an agents of the imperium codex. Sisters of silence are already in plastic, much of the inquisition can be done by kits for
IG, so sisters is the logical part of the codex to get some love.
In the 7ed "impiral agents" codex were these factions (not all of them had their full list but only parts of it) Cult Mechanicus, aeronautica imperialis, astra telepaths,
SoB, Deathwatch, Grey Knights,
LotD, Assasins, Inquisition. In the book the only ones that would have had a full list in it would be the
SoB, Inquisition, Assasins, and Astra Telepaths. The others were parts of other factions that already had Codexes out.
In 8th edition ones that are obviously getting their own codex - Space Wolves, Orks, Harliquins, Genestealer Cults, Ynarri, deathwatch. Knowing
GW Knights are probably getting their own codex as well. That leaves these impirial factions in a guessing game as to how and which ones are getting their own codex or combined into an "Impirial Agents" codex - Inquisitors,
SoB, assassins,
LotD,
SoS, ministorum priests. (though arn't the
LotD covered in the new space marine codex?)
