Did the devs say anything about upcoming patches?

I have not heard anything about it. They generally proceed a new DLC and we have no word on any new DLC's either. We just haven't heard that Dragonborn was the last one, so hopefully it wasn't.

Yeah i hope DB wasn't the last one! I just deleted Dawnguard and hope for more content like DB

But some major patch for Hearthfire, DG and DB would be cool, too!

I'm getting ready to start a new character myself since I can now retire again my main guy after finishing DB. I am heavily debating disabling DG also. I just can't stand the damage that DLC does to the vanilla game and I'm not sure the extra little side quests and crossbow is worth going through all that hassle to finish the DG MQ asap. There is just so much they did wrong in that DLC ... starting with making a DLC that catered mostly to Underworld fans. Bite Them.
