Where will we find ourselves in Thedas for DA4?

Given the knowledge from Trespasser DLC, it is worthwhile to speculate that a large portion of DA4 will take place in a potentially war torn Tevinter Imperium and/or Seheron while the Imperium and the Qunari duke it out. Let's not forget about the elves though and the huge role their lore will play in DA4, hence Elvhenan. However, this is not set in stone and BioWare could take the setting for DA4 anywhere still at this point. 

That said, what settings and environments do you think we'll find ourselves in DA4 and why? Or if you have no idea, where would you like to go, see and explore?

I personally think DA4 will travel away from the typical settings of Ferelden and Orlais and largely stick to Tevinter and other elven and Qunari regions. I am currently under the impression DA4 will focus on the war there and also the elves and their ancient roots. Although, I would love to see more of Antiva where Josephine Montilyet comes from, the Free Marches where the human Inquisitor Trevelyan hails from, Rivain where Vivienne is from and of course, Nevarra where Cassandra Pentaghast has her background. 

Anderfels- An arid, dry and hot kingdom in the northwest. Birthplace of the Grey Wardens. Once ruled by the Tevinter Imperium.
Antiva- A warm, wealthy seafaring principality to the east. Lots of wine and vineyards. Lacks military, but is protected by the dangerous House of Crows. Qunari even leave it alone.
Elvhenan- A large and ancient, dead elven kingdom. Arlathan was the crowned capital located north of Antiva, near Tevinter. We might have visited it in Trespasser DLC unknowingly via the eluvians. 
Estwatch- An independent island stronghold to the far east known for its strategic position. It was first settled by the Tevinter Imperium, then taken by the Qunari in their wars against the Free Marches. Raiders now occupy it.
Ferelden- A cool, temperate kingdom in the south. Setting for the previous DA games. 
Free Marches- A temperate central region that consists of a loose confederation of independent city states descended from barbarians that frequetly raided northern Ferelden. 
Nevarra- A strong central kingdom once part of the Free Marches and Tevinter before it quickly grew in power and became sovereign. Known for its art and intellectual thought. Greek/Roman styled architecture and clothing.
Orlais- An empire in the southwest. Currently the most influential and powerful nation. Setting for previous DA games.
Orzammar- An underground dwarven kindgom. Setting for previous DA games.
Par Vollen- A tropical far northern island. Once inhabited by a primitive, sapient species known as the Fex prior to the Qunari arriving, replacing Tevinter rule and making it theirs. Humans may have originated from here.
Rivain- A coastal northeastern kingdom making up a peninsula. People here have darker skin and pride themselves as tattooed seafarers. Place emphasis on community over individualism. Do not believe in the Maker or participate in Andrastian traditions. 
Seheron- A humid jungle island nation to the north. Previously under control of the Tevinter Imperium until the Qunari invaded. It has fallen multiple times and bounced between being occupied by Tevinter and the Qunari. 
Tevinter Imperium- A lush and powerful, decadent human magocracy nation to the north. Once unrivaled in strength, influence and power in nearly every corner of Thedas. Warred with the elves and burned down Arlathan with blood magic.

*Fun reminder: Thedas is a continent in the Southern Hemisphere. As you go further north towards Tevinter, it will become more hot and humid consisting of jungles. As you go south towards Ferelden, it will become cooler and temperate.
