Ok, as someone heavily involved in the warhammer hobby;
No. For a few reasons.
The first most important reason is that Warhammer Fantasy no longer exists as a property. It's all been ported over to "Age of Sigmar". Infantry formations no longer exist. Point values no longer exist. There is no balance, it's all made up rules to made up limits.
The second is that GW will give out their IP to literally anyone who wants it. There is no reason to believe this will be good beyond that Creative Assembly is working on it.
Third is that yeah, they're packaging the core factions (chaos) as forgetin DLC. That is a warning sign, folks.
