Idk, the communication was much better pre-EA release.
I'm guessing they've run into a few major problems that they don't quite know how to fix yet, and that's taking up all their attention (as well as making it so that they can't provide a precise time estimate for the next update).
I am sure that things will improve on the communication front.
I'm not sure they want to keep us informed every day of the progression. It's EA, still very early from the final release, they probably wish to address each story by priority, and release an update whenever there is a stable revision. And they did post an early heads-up that it would be coming, and how to prepare for it.
So I'm not sure what else you'd like to be informed of?
As for the guessing... I'd probably not venture too much without knowing anything at all of what they are doing right now
