Koji Fox is on record as having said that we will find out what is under Silvertear lake this expansion and that the Heart of Sabik would make its return as well this expansion. That to me clearly indicates that even with the Dragons dealt with we will still have something the Ascians still to play out and quite possibly the Garleans too. The Garleans are master manipulators who are implied to have even set the events in motion that lead to the fall of Allag and the following calamity. Very few people can even sense their presence if they don't want to be seen. It would surprise me greatly if they didn't at least have a hand in what the Garleans are up to. The Garleans are one of the biggest pieces on the board and there are 9 Ascians that have been out there working that we have seen no sign of. If the Ascians were able to screw with the Allag then they would be able to do similar to the Garleans.

I suspect 3.5 will end with some type of climax against Elidibus that sets the Ascian plans back, at least for a while. I think its only recently that they have actually started to see us as a realistic threat. They are complacent in a way only immortals who have had thousands of years of continued victories can be. For them victory was pretty much assured. We have been a problem but not a true opponent. I think 3.5 will firmly set up the situation where the Ascians realise that the war isn't over yet. I see them stepping back and regrouping after this.
