>>108856886Yeah, the old model's obsolete and can't really be rerigged the way it was cut, so she'll need to redo it from the ground up.
That said, the design itself isn't dead. She already has a new, holo-quality 3D model for it and used it in her birthday concert. It's gorgeous in motion but it'll probably be seen more as a celebratory or gimmick thing for retro streams until she releases the files for it.
Knowing her, she probably already has an updated, redrawn Live2D just sitting around in a folder waiting for an event to pull it out (like she did with the various chibi models she revealed at once a bit ago)
