I don't think the Overwatch project is going to be released this year (I hope I'm wrong). I'd say it's more than halfway done, but it definitely still has work to do. I feel like this could be their masterpiece.
Im huffing cray ammounts of hopium, but looking back at his other proyects, I have a good feeling it will either release on new years, or by january next year TOPS.
For the latest Bordello, the last set of WIPS Nyl released were 3 months before he released a trailer (december 1st, and then released thw whole thing on the 31st)
For Lyria, the time between the last set of wips and the forst trailer was a little under a month and a half (in this wips he did specify they they were the last). However, the trailer for that was dropped on Jan 4th of 2022, and the whole episode dropped shortly after on the 8th.
By that logic, and the wording on this wips being the FINAL ones before release, a realistic expectation would be for the trailer to be dropped by the end of the month, and seeing a while release by the first two weeks of 2026
(Or let me inhale some more hoppium, a trailer December 25th and full release on new year)
