Why would you be disappointed in a technical update? It means new scenes are not the focus. Frankly when it does go live, I don't expect much new content with a technical update. Which they said from the beginning would take them a long time.
I agree with you until your last sentence.
Dark Cookie, when making the pitch for the Tech Update at the end of 2020 and start of 2021, told the paid patreon subscribers it would
"take roughly the same amount of time (3 to 4 months) to complete." Subscribers then voted in the poll for which should come first, Rhonda's update or the Tech Update, with that understanding. Obviously, DC was wildly naive, mis-/under- informed, fantastically optimistic, or simply clueless about the resources (time, staff, etc) it would take for the tech update to happen properly.
The Tech Update was going to be worked on, no matter what. It was only a matter of when. Even if subscribers had voted for Rhonda's update to come first - that would have been done by August 2021. The work on the Tech Update would have started right after that, with Annie and Judith's updates still in the future. The only difference is that Rhonda fans would have had her content this entire time, rather than waiting along with the Annie and Judith fans.
It is what it is and we'll see how it is when it is released, whenever it is.
