I think we'll see villages like Redcliff, but not any actual metropolis like Denerim or Val Royeau. Skyhold is going to be a huge hub and very much like a mini-city with tavern and merchants, etc.
Big cities are kinda hard to do well in video games because they don't have the resources to populate hundreds of different buildings to do them justice. Kirkwall and the cities in Skyrim both did a good job, but both required a willful suspension of disbelief. Kirkwall required you to take it for granted that only a small portion of each city area was available to you and your party, and the cities in Skyrim were really too small to be true population centers (though they did a good job of giving the illusion that they were larger than they really were).
