This probably isn't the most exciting news in the world for everyone, but there were things announced at Warhammerfest which weren't from Forge World! Here, for example, we have a new app, called simply "Warhammer: The App".
So, in fairness, it's not all that exciting. It's just an app which will provide news articles about Games Workshop's recent and upcoming releases. However, what got my interest was a mention that there is a reasonable chance that it will also sometimes have exclusive free content, such as missions and similar.
