This is something that's been in the planning stages for a long time. I'm not sure if it's actually confirmed for production or not.
Anyway, I don't have any details, but my best guess would be don't expect articulation, or at very best only extremely limited articulation. While Yamato do make a lot of Character figures for other animes, most of them are little more than fixed pose statues, so expect a similar sort of deal.
I think if it gets made, it will probably be something like the standing Banpresto Miria, which is shown in my Q-Rau review, but with hopefully a better sculpt.
