My low stakes conspiracy is that like how they ran CYL early in 2023 because they figured if they ran it at the usual time when FE Engage came out it would be just like 3H's release and just be the 3H show, they're fucking with any FE information vis-a-vis the next CYL event specifically because of Engage.
Now they have the opposite problem of 3H's sheer dominance, so they're deliberately delaying the announcement of any FE4/FE5 material(e.g. the conspicuous absence of FE4 or FE5 characters while every other FE MC is in the Switch 2 avatars).
So after two consecutive Engage shutouts they're going to try to stay quiet, run CYL 10, one last chance to get any Engage character over the low as fuck threshold, and then finally announce something about FE4/5, even if it has an uncharacteristically aggressive release date.
