Don't worry. Even if there's no Gencon Update for Armada... remember that last year they waited a week AFTER GenCon before announcing Thrawn and Wave 7.
It might make business sense for them to wait. X-Wing 2.0 is launching, so from a certain point of view, having another announcement for a competing game MIGHT not mesh well with whatever they DO plan to announce.
So just in case we don't see an Armada announcement at Gen Con - give it at least one more week before the panic kicks in. And if you are there, find me and hold my hand because we'll need to join forces to stay strong. Maybe summon Captain Planet or something.
