That´s the first time from I know that Paradox don´t give an Update DD after Holliday. But it´s Corona-Time and so we all have to be exercise patience.
They have to work from Home (like seen in MW 5 Merc: DLC-Update in an Skype-Intervew) or only 1/3 of the Crew is in the Office like the TV-Host, Radio-Host, offical Hosts etc.
So we can´t expect an Dev Diray so fast. I personaly think the Devs concentrate on the next Patch and small DLC to bring it out this year with the atm last overworks for the Navy and the big overwork for the Airforce for 1.10 "Collie" and the begunn big rework for Patch 1.11 "Barbarossa" for the Army, Supply and much more things with the other Part of the Team.
And if we get an Dev Diray, we will see it soon enough. It´s nice to get surprisses with new Infos. So I and many others with a lot Bereath (Paticance) can wait.
There are other Games you can play or you play Hoi 4 with 1.9.3-Patch, all existing DLC´s and Mods until the next Version comes up.
