It has been an extremely busy time so that doesn't surprise me. Without new information being released conversations either stop or end up being about things covered already. Once things slow a little I would expect more info to be released.
On a similar topic, my recent computer crash lost a DLC for Dragon Age. I posted a question on the tech forum and my post was at the bottom of page 2 in about an hour. And that was just the tech support forum. Talk about forum action. I haven't even peeked into the regular forum. If I thought us war game people were geeks I can only imagine what things are like in there.
Clientelle is only part of the equation. Forum administrators having clear respect for the people who post there make up a large part of the difference about how well a forum is frequented. We've talked about BFC in that regard but there are better examples. I noticed boardgamegeek just reformated and put all the wargame stuff in a "subdomain". Not a bad idea in itself, but there are no intuitive visible cues in the main site and forum areas, so it's like a puzzle hunt to find the new forum area. There was no discussion that I recall with forum members. They just kind of "Facebooked" everyone and redesigned without any notice. It's their prerogative, and it isn't a horrible change, but users can feel marginalized pretty easily without at least a tiny bit of consultation beyond vague "news notices" in the support sub-forum. The most popular image uploads there also seem to be the ones where losers - I don't like that term and tend not to use it much but I can't think of a better word for it - take photos of their teenage girlfriends in tank tops or unbuttoned blouses sitting at a gameboard, and the horny admins feature said photos on the main page of the site. Basically, cheap stunts to drive up the page views, I am guessing, and increase advertising revenues. The forum stats in the wargame section there have been dropping off in recent weeks, and the most recent events will, I think, further serve to subdue them - and of course, we're heading into summer in the northern hemisphere which will also dampen enthusiasm for indoor pursuits, or at least one would hope.
The best forums are the ones where the administrators have some respect for the users. Don may have reformatted here a bunch, but the level of communication has been high and is actually improving each time, and the moderation in this sub-forum is consistently good. But of course the traffic volume is low so that's probably easy to do.
