I wouldn't get hopes up of new warriors or anything other than a model or two. It has been a stellar year for AoS with, including a StD book, 12 battletomes!! That's crazy.
What it seems to be happening is that GW is setting the groundwork, getting the books this year which gives them freedom next year.
We could see lots of new armies but I suspect we'll see things along the lines of campaigns and supplements that could come with replacement models for armies, much like the blood of the phoenix for 40k.
Again tho, 12 battletomes!!! That's insane!
