Has anyone given a bit more thought to what class we are getting in year 3

I have been thinking about which class we could get, and honestly they all lead to chaplain, we are getting a one handed thunder hammer, which may or may not be the model which is to be used for the Crozius Arcanum, we are also not getting the greatsword or at least not yet which means for now judiciar is of the table, we are also supposed to be getting a champion pack for the new class, and the chaplain is famous in at least 3 chapters, blood angels specifically the death company chaplains, the interrogator-chaplain from the dark angels which would be my best guess, and then the black templars chaplain, as for the apothecary, i could not, for the life of me guess a chapter that they are famous in, i mean i guess the red scorpions but i don't see them pulling out such ball knowledge on the basis that it is not very popular or well known, terminators i would assume we are not getting so no deathwing, and librarians would work with the blood ravens but they said that they are not adding librarians so idk, i can't think of another class that we could get, and even from a role standpoint, we got a tank (bulwark), we got an assassin (vanguard), we got a mobile melee (assault) we got a heavy weapons specialist (heavy) we got a ranged specialist (sniper), we got a generalist (tactical) and we got a caster/engineer (techmarine) and the missing piece, a leader, which is exactly what chaplains are
