A plastic Jabberslythe has been long overdue. Though it looks a big model, which means it'll likely be expensive, it's still a definite upgrade over the Finecast one which is allegedly notoriously difficult to put together.
And if we're getting a Jabberslythe, we may well be getting some more stuff too!
Plastic Centigors?
Plastic Chariot Kit that can be built as a Tuskgor or Razorgor chariot?
Separate plastic Razorgor 3-model kit?
Plastic Cockatrice?
Plastic Beastlord?
New units? (Perhaps stretching it given we have quite a lot of variety for an AoS faction, but a possibility)
The one thing I hope they don't do is remake some of the existing plastic kits, because the Minotaurs look great in my view, and the Gor, Bestigor and Ungor kits are not only pretty decent but I also have some of the latter two and don't really want GW to suddenly replace them with a new aesthetic that wouldn't fit well with the ones I've got.
But otherwise, the True Children of Chaos are about to get the recognition they deserve!
