It's been months now since the release of the last Dragonborn DLC wich was in november / December if not wrong ? So no news ?

Well know most likely in May/June. Itll give the PS3 and PC players a chance to play the new DLC through.

That woudl be a release date time , but they could announce it befoure no?

Nobody knows I suppose.

To be fair, the length of time between announcements for Dawnguard and Dragonborn was about six months. If memory serves, Hearthfire was announced at the end of August and only had a week until release when they announced it. Going off this precedent, we are due for a small DLC but nowhere close to an announcement of a larger one.

Dragonborn came out in February.

not for xbox users.

Perhaps we'll get some news at http://www.bethblog.com/2013/03/08/the-elder-scrolls-online-descends-on-boston-for-pax-east/

No news, my guess is they might announce it near, or at E3?

There are already threads about DLC speculations, like this; http://www.gamesas.com/topic/1450205-is-it-foolish-to-think-there-will-be-more-dlc/
