I've a feeling they're not releasing any info, because no matter what info they give, people will flip out.
If they say "it'll be ready in two weeks", and it's a minute late, people will freak out.
If they meet the two week deadline, and anyone finds a single bug, people will freak out saying they rushed it.
Any action they take, will hurt the community. It'll be ready, when it's ready, and people will return when the DLC is released. It's not like people are cancelling subscriptions, or are wasting subscription time waiting for the DLC.
They are not providing info, because there is no concrete info, it's not like baking a cake, you can't just look at the stove to see how much longer it'll take. Some bugs may take time to fix, and that time is uncertain. Better they take their time now to fix as many as they can, and polish it to the best of their ability, than to rush it out the door and have people complaining.
