FoG 2 didn't really have much faster DLC release rate. From the Steam premiere dates:

FoG 2: 2017-10-12
Immortal Fire: 2017-12-05 (2 months)
Legions Triumphant: 2018-03-08 (4 months)
Age of Belisarius: 2018-06-07 (3 months)
Rise of Persia: 2018-09-27 (4 months)
Wolves at the Gate: 2019-05-30 (8 months)

FoG: M: 2021-02-04
Reconquista: 2021-05-20 (3 months)
Swords and Scimitars: 2021-09-23 (4 months)
currently: 2.5 months since last DLC

Basing on the history, I would guess, that next DLC will be in a month or two if they keep up the pace.
