I don't want to see anything more that has to do with templars and officially trained mages, and darkspawn.
If the qunari are to invade, I want it to become a real war simulation. To focus more on macro rather than do something ala ME3 where you do random missions to increase Assets that you don't ever see, don't know/understand the logistics etc.
I want to break away from the established lore and deal with something alien. Perhaps an ancient evil that does not originate from the Fade and the sins of mages. Or smaller scale with big creepiness factor. Try some horror survival squad based genre or something. ^^
The breach while it's grant, it's not that special. It's revolves around things we already know a lot about. Even if it has a twist, it's mostly familiar territory. We may be surprised but I don't think it will have lasting value.
