Yeah, they were announced at an Age of Sigmar Open Day, which are special events, so of course they're going to tease something for further in the year. Crazy I know, right? 🤯
In the meantime they have a release schedule, and other product slated to be released. They don't tease everything with a few months wait time. So you'll see new stuff previewed and promptly released. Meanwhile people are coming up with conspiracy theories like GW is ashamed of the battletome, there's been a huge problem, etc.
The only problem they've had was cutting all those miniatures without some kind of statement beyond an email asking you to buy the stuff that will soon be irrelevant.
Y'all need to cool your jets.
