On the bioware forums, the developers frequently enter discussion in the forum, which is kind of cool. I understand that was once something bethesda did as well, don't know why they would stop though. I got a feeling it has something to do with the ever burning flamewars between games.
That was a huge factor, a moderator on the forums told me until oblivion's release the developers were actually quite active on the forums, then the more egotistic modders (mod makers, not moderators) decided to step-up and claim a bigger piece of the pie to themselves, some started talking as if they were the ones who made the TES series in the first-place, they started demanding the construction kit, making sarcastic comments like how they fix the real bugs of the game (unofficial patches) and how they were the ones that were really behind TES games. It is understandable why the developers started to slink into the shadows after that ordeal. Maybe one day they'll forgive the forums for what some did before, but right now, i bet they're wondering whether we deserve it anyway. -_-
On a lighter note, this might actually be an incentive for them to make an awesome game for the next TES, and maybe they will one day become active on the forums, who knows ^_^
