For context on how long "the Filian official model has been done" I remember her showing her friends the model in DMs back when Saruei used to collab with people.
"Done" at least conceptually, since making high level 3D as an indie must take an extremely long time and now she's got high level face tracking and new tech.

Yet again, I have respect to Filian not doing what so many chuubas do and air out all the drama in DMs and Google Dockeys and all that cringe stuff. This situation has been resolved for many months and now that things are good she can just drop a little behind-the-scenes lore. Towards the end of the relevant part she mentions that she's going to be getting the new model approved by the current artist which does have me thinking that maybe it'll be really similar to current Filian, which we all love, but yet again it'd be sort of anticlimactic if she's a "vtuber in training" and also one of the top largest vtubers in the world yet she waits 4 years to officially debut a model that's 99% like the current one.
