They released the preliminary notes for Heavensward just 3 days before the start of that early access, a mere two days difference to when we have the prelim notes for this expansion. You're seriously getting worked up over two days difference?

Also, the communication with journalists is a two-way street - they get the information from the live letters and other such events (which despite your description revealed new information each time), which influences the questions they ask, and then SE has to be willing to answer those questions...which they have for the most part, though with their hallmark caution of (compared to the reveal nearly everything approach of some or the reveal next to nothing of others).

Seems like you're really reaching to be upset over something.
