At least it’s not like Bethesda’s Elder Scrolls 6 “announcement.” They didn’t even confirm they’re working on it, just that they plan to build it at some point. According to Wikipedia:

The game entered pre-production by 2018, formally being announced during Bethesda’s Electronic Entertainment Expo (E3) 2018 conference. The game entered active production in 2023 following Starfield’s completion and launch.

So they announced it 6 years ago, but nobody was actively working on it until last year. Yet for some reason they decided to release a teaser for it.
