Early october 10.2 is entirely possible.
It would be the same timespan as 10.0 (28 nov 2022) - 10.1 (2 may 2023).
That could put a potential 10.3 somewhere early-mid march.
Then the fated season could start anywhere mid-late september, which means there is still a tiny bit of room for a short fated season until the next expansion releases. Fated season could also be part of pre-patch 11.0. Expansion could then also release in early 2025.
The other scenario could be no 10.3, but in that case I would assume: fated season early-mid march, which will be a shorter season like S4 was in SL. around 4,5-5 months. And then 11.0 releasing somewhere in august 2024.
Either way: Too many variables to predict 10.3/no 10.3 very well. It depends on the next expansion release too. Since it is 20th anniversary, it could be bigger and we could be looking at option one. On the other hand: 10th anniversary got us WoD, so it could just be another "new island" expansion that would release summer next year.
I've never been this clueless on what the fck to predict is going to happen and it's honestly a lot more exciting.
