Well, if you didn't give any attention to their marketing, how can you complain that it was misleading? There was no doubt that the announcement concerned Warhammer, especially after CA itself
clairified that the hint is about Warhammer's future. There is no point for a company to give hopes to its audience for something that is going to be revealed very soon, which is why for the entire misunderstanding, wishful thinking and not sneaking PR managers should be blamed. Not to mention about unofficially provided
proof. Since 2015, when CA's plans about the Warhammer trilogy were first published, it was made clear that the next three games will involve fantasy. Releasing simultaneously (thus almost doubling your expenses) two competitive titles is financially suicidal, despite any claims of CA that a separate team has been working with history titles for
two years. That is an obviously false (or at best, highly misleading, because two employees brainstorming could be defined as a team) statement on behalf of CA and a valid target for criticism. Even that claim shouldn't be believable from the begining, given the basic rules about profiting I mentioned above.
