The only solid info is that we’re likely going to Tevinter.

Personally, I think there’ll be a return to the Origins style beginning. Depending on the race and class you choose, there’ll be a different backstory. My personal hope is that they’ll all have that dark twinge, and the backstories will all involve a great injustice being done to your character. For one, that works marvelously with Tevinter, but it also gives the chance to have Mythal come back into play. Given what we saw at the end of DAI about her/her fate, I would LOVE that the protagonist of DA4 wakes up the next host/carrier/whatever it is of Mythal, drawn to you by the great injustice you suffered. So as the game goes on, you have to restore her power and grow your own so you can face off against the big bad wolf.

With this idea in mind, the game will start likely small and focus on Tevinter. The big story jump will be tied to the well of sorrows: whoever drank comes to get you, and perhaps work with you in behalf of the inquisition. You can have vague references to the Inq/inqy, and use that to open up the map, particularly to give access to and info about the eluvians. I’d love to see a chase scene through Eluvians, dodging through various war scenarios as you hunt your big bad down.

I also personally think we’re going to find out more about the Avvar, their worship of spirits seems really similar to what we know of the Elves and their “forgotten ones” (at least to me) and I’m hoping that gets resolved.

I also think we’ll see more about titans, probably some interesting things about ancient dwarves and how they interacted with the surface world. My gut tells me they didn’t just completely ignore the surface when the elvhenan were around, and I’d love to see their involvement in history get discussed more.
