In an interview they said that there were no dragons at this time. They were wrong. There are 4 dragons that escaped annihilation. One is obviously Paarthurnax who waits on top of the throat of the world. Another is lairing in Morrowind and goes by the name of Ahbiilok. Another one is Mirmulnir (the first dragon you kill in skyrim.. interestingly, it is likely that he wasnt revived by alduin. He just came out of hiding once Alduin returned.) the last is Nahfahlaar. So there are dragons.. http://www.uesp.net/wiki/Skyrim:Atlas_of_Dragons, http://www.uesp.net/wiki/Skyrim:Mirmulnir. Maybe it is possible that we will encounter some of these (obviously we wouldnt get to kill two of them, because one you kill in Skyrim and the other is important.). I dont know if the developers of TESO (Zenimax) know this but it is part of the lore. What do you guys think about this?

You forgot the one in the soul cairn and blackreach.

I don't know if we'll encounter these specific dragons, but they did mention in the interview that there's a possibility of the dragons coming back at this time period. We'll likely have an expansion for them, which I'm not against, but not really excited about either. I know people love dragons, but I can live without 'em.
