I realize that most folks would like to see more posts from the actual programmers on the forums. (I'm not a dev nor do I play one on TV.) While I empathize with that desire, you also need to look at it from the overall community perspective: Rumors start easily within the community without devs possibly adding to the fodder.

Our team is proud of the work they do and are more than happy to talk about it. They also like to talk about the possibilities of the game--all MMOs start out as a simple possibility, after all. That's also where the danger lies.

The current perfect example is the Zen Master Discipline. This made it out onto QA Test and it has been a recurring topic ever since. Several times now, I've stated that Zen Master is nowhere near entering the live game. However, I've seen posts as recent as today talking about it arriving in the next patch.
