I noticed something. With the previous dlc's the announcement trailer was to be viewed on www.elderscrolls.com right at the first day.

With Dragonborn this is not the case. Something to do with microsoft's exclusive contract perhaps?

All I know is on the Bethblog, it only states the 360 and Dec. 4th.

However... the game is ported from the 360. So we might have to wait til they are done porting it to PC. (Sorry PS3 players.. it only makes sense for them to give you DG first before Dragonborn..)

It'll be xbox first then pc.

Its definitly coming to xbox first. I use both the xbox and the pc and i like both, but, i think bethesda should realease dlc for everyone on the first day even for the ps3

I have only heard the the xbox release date so far i agree that they should be released at the same time but pc usually comes after and there is no world on any dlc for ps3 so far apart from that it is coming

At this point in the game, don't bother even considering a ps3 release as plausible.
