What we know is following:
The Devs work on Patch 1.10 "Collie" and Patch 1.11 "Barbarossa" paralley. How many % works on Barbarossa we don´t know. Maybe one of the Devs will show. But 1.10 "Collie" will come first, what the Patchnumber says already.
If I read the first DD´s correctly the Devs announced there that the Codnames of the Patches stand for an Operation the Axis, Comintern or Allies did. And if I read the last DD correctly, the Devs sayd about something about the 2 upcomming Patches.
So if the announcement of the Codenames are correctly, Patch 1.10 "Collie" will be the Pacific-Part with not yet fully done jap. Colonys and Oversee-Islands, which was an Operation in the Pacific against Japanise Oversee-Islands. The other Reason why this will be done first is that there are not done Allied-Colonys too [British-Malaya, France-Indochina, Nederlands-Malaya or so] and the Airforce-Part (Priority) will be refited first as well as the last big Points of the Navy-Part.
The Codename of Patch 1.11 "Barbarossa" ilustrate themself. That means Europe (Italy, Poland, UdSSR, Bulgaria, Slowakia and such). There will be done the Army-Part, Supply, Industry etc. which is a much harder nugget then the Airforce or the Navy.
So if all goes well I think we will get Patch 1.10 "Collie" with a small DLC at Years-End or the first 3 Month in the next Year and a bigger Patch with an big DLC at the End of 2021.
