Last pack was 71 days after the previous.
I guess we can't exept the same for the next one.
Last few packs were approximatelly 170 days between each other.
The ones around year 2024.
Most likely we will know better after Frontier Unlocked 30th.
Otherwise I was just playing with calculations and if next pack would be those 70 days after the last one it would make beginning of September.
170 days would make first quarter of December.
We were used to get 4 packs per year until last year (2024) where we got only two with ending-like felt Zookeepers pack name.
We don't know what will be the strategy for this year. 2 packs? 3packs? 4?
We started pretty fast this year for 2 and 3, didn't we?
If they want to keep 4 DLCs per year, August/September and November/December each would be only option right now.
Just some thoughts

open for discussion.
