I also really want to see the Advent starbase. And I want to play Entrenchment! I LOVE defensive structures. It's almost a little bit weird, to be honest.
But I understand why we're not allowed to know their estimated release date. It's because we misbehaved the last time we got one. The bottom line is that it'll come out when it's ready, not before, and all we would do by squeezing a date out of them is possibly guilt them into releasing it before they're ready. And then we would be angry all over again.
Whoever said "good things come to those who wait" probably didn't mean to imply "...and whine constantly about what they're waiting for."
