Dang I forgot about the Arid pack having a 14 day gap, this is tricky now…To add onto this.
Frontier switched up their reveal-release schedule last time. Usually there's about 14 days between reveal and release, giving us an entire week between reveal week and release week. Last time however, it was 7 days. No idea if this is a permanent change or a one of, but still, it's a change nonetheless.
If Frontier is still doing their annual two week break at the end of the year, that might mean that we get an announcement next week and a release right afterwards; because if they don't they barely have time between release and their break to fix urgent bugs.
We know that there has to be at least a 9 day gap (8 screenshots + developer journal) assuming this next pack is an animal pack.
I also forgot about their two week break, so I think the pack has to be released on the 12th, with a launch about two weeks in advance, that being the 28th of November. On the other hand, grasslands was revealed on a Friday with a 10 day gap I believe.
So overall, we probably have a 90% chance of an announcement this week, either on Tuesday or Friday, it also depends if there will be a livestream. If there is, it’s gonna be Friday.
