Whatever dude. GW clearly benefits from the Warhammer Fantasy license, and the remarkable success of the Warhammer Fantasy license elsewhere does not go unnoticed by GW (as evidenced by their continual use of the license).
Will they ever support it as a tabletop game, if even just as a Horus Heresy-style "minigame" based off the AoS rules? Maybe, maybe not, who knows? Releasing stuff like Warhammer Legends at least denotes GW's knowledge of the fact that people WANT Fantasy stuff. And where there is money, there is opportunity.
Unless your a GW dev, you have no more knowledge of their plans than I. And I admit, I want them to support Fantasy alongside AoS. And there is evidence they are supporting Fantasy, even if its only through open play rules, made to order models, and licensed video games/pnp rpgs. But the point is, and bear with me here because its hard to understand, they ARE supporting it, and they ARE making money off it.
So if they continue to make money off Fantasy as a tabletop game with more support, howecer cursory, it would not surprise me. It would also not surprise me if they dont support it. But the potential is obviously there.
