Q2/3 2025 still gives Inart a little time to get a prototype of Frodo and Sam together, and beat JND to announcing... well, half the hobbits. Assuming that Legolas is being put up around October, an announcement of those two Hobbits could be six months to nearly a year later and still match up with JND's timeline. I suppose the Nazgûl could get in the way, though.
Have they confirmed that they're using the Potter molds for the bodies? That sounds wrongheaded to me, there's no way that would be close to being in scale.
