I understand the optimism, but it is not to me, I always joke about the Chaos Dwarfs but it doesn't mean I am expecting to receive them sooner or later. It is not because I hate the game or anything like that, I play a lot of my Chaos Dwarfs and it is the first time they have a real ruleset since they existed.
My point here is that I am talking about the little I know, that GW works on long iterations and the specialist team more. After all, they are working on a lot of games at the same time.
I want Chaos Dwarfs but I understand that working only making small releases like they are doing right now is not profitable in the long term, they need to produce new things that have a good attachment to most of the players or the game will die soon or later, that's the Horus Heresy, Blood Bowl or Necromunda strategy.
