Not yet. I'm in the middle (alright early middle, not even at Skyhold yet) of my second playthrough. Depending on how drained I am by meaningless fetch quests by the time I'm done with this playthrough I may do another (So far I've done a human who believes in the Chantry, and this run is an Elf who doesn't like humans very much, although her attitude is changing as time goes on). I want to try a Qunari, plus I want to try a dual wield rogue, a Reaver, and pretty much every other spec too, lol.
Sometime soon I will also do another DAO playthrough. It's been a while since I've done a Warden who romanced Morrigan (my 'cannon' playthroughs usually romance Lelianna), and I need Loghain alive because I love him.
It is very, very iffy whether I will play DA2 again or not. I've pretty much done everything there is to do in DA2 and its just so long and such limited environments. I'd love if Bioware eventually did a DA2 remastered, with a new title Dragon Age: Champion (cause numbers suck), and actually made the city change as time went on based on your actions from previous acts (plus in Frost Bite I'm sure Kirkwall would be pretty), but until then I think I'm gonna be fine skipping DAO.
Once DA4 is officially announced I will probably do a 'import' playthrough of DAO (again lol), maybe DA2, and DAI.

You can probably tell how much I love this series....
