It's a little sooner than we were predicting, but Unity of Command II's first DLC pack will be storming over the maginot line next week. 2x2 games shared the good news today via a new development update which also goes into more detail as to what free quality of life changes are coming, as well as the DLC features.
Blitzkrieg itself will feature 25 scenarios, only 13 of which are historical in nature and cover the period between 1939-41. Apparently a lot of work went into researching these scenarios since there are a lot of nationalities involved; some of whom are only featured once or twice.
In terms of free content, there's a quite sizable quality of life patch dropping at the same time as the DLC. A major balance issue from before the base game's launch has finally been fixed, and there are several new additions as well including designer notes and the official insignia for each of the campaign's HQs, and other UI improvements such as tool-tops and stats for en-route units.
In terms of other premium mechanics, there are new HQ abilities and theatre assets coming as well:
