They said that they'll be working on 2 DLCs at the same time so it means instead of 1 DLC in a year, it'll be 2. So hopefully, they release 1.10 in September or something and then the big Barbarossa in late December to January next year.
I think you're wrong and I don't think we'll see dlc in a short time
They only said that they were working two patches in parallel, the 1.10 Collie and the 1.11 Barbarroja and saying the latter would be larger than the first therefore saying this will surely come accompanied by an annual dlc
remember that last year they did something similar with the launch of the new launcher that came another new patch that was not accompanied by another dlc I think that 1.10 will surely be released for November as they did last year with the new launcher that was accompanied by another patch
On the other hand, 1.11 Barbarroja I believe will be launched in February together with a dlc
I also think that the game developers have come to the conclusion that the best thing to get out of a big annual dlc and small flavor packages on the anniversary of the game and people are happy with that policy after the harsh criticism they had on the first dlcs
