A quote from Netheos that he posted last Wednesday on Discord:
"We have a blog about the lore and story, and a bit more details about the synopsis of the three campaigns coming this week (we're waiting for the last approval to publish it). We continue to work on videos introducing iconic ships from the game. An announcement with the exact date of the Beta will arrive later this month but no set date to announce here yet. Things are on their way "
He quoted himself on Friday about midday. Then he went home without a word. And this is not the first time we have such a situation. It is a quite standard procedure for them to announce something for "the end of the week", then silently go home and pretending that nothing has happened. That shows how honest and how much regard they have there for their community and customers.
Yes, they can still wait for the approval. But has GW prevented them from informing about a delay? Really, they can't afford such minimum of decency? Apparently not. No thought for a moment if there is some other branch that does such stuff to there customers.
