BU/HYYH lore

I was a bit of an inactive ARMY last year, so I’m kind of behind on things and had a few questions.

I saw people saying Bang PD announced a 10-year anniversary HYYH project for 2025. Did that ever actually happen? I heard people speculating about notes pt.3?

Also, do you guys think the BU storyline is still ongoing? Even the albums after HYYH still felt connected to the universe in some way, but from what I’ve seen so far, that doesn’t really seem to be the case with the new Arirang concept. Did they completely abandon BU? Idk when I search it up it says it’s still outgoing idk. I’m honestly hoping we get more BU resemblance in future projects
