Hmm... Just finished Descend and replayed JoH.
Another new DLC this week is surely to much to hope for?
Yes and no. I thought it seems very quick myself but then when you take into account Bioware Austin made Descent, and that Bioware Edmonton was freed to work on "moar content" it is feasible that something for single player DLC is close.
I am fairly certain at this point IT IS single player content as they just released the Darkspawn MP content. I don't know what else could be on it's way other then announcing there is a large scale DLC or expansion.
Expansion may make sense since they have Qunari (apparently based on survey leak), Solas, and potentially other things like the new Divine to touch upon. They may want/need something large like an Awakening expansion, although if that was the case, maybe the gap between JoH and this DLC is too small to create such a large scale DLC. It could simply be the announcement of such content though, and maybe to expect it in November or December...although we've never had that type of gap in between the announcement and release with DLC with Inquisition so far. I am kind of rambling now
