I expect we'll see more Storm Coast/Fallow Mire/Exalted Plains/Emprise du Lion type planet maps than Hinterlands/Crestwood/Western Approach/Hissing Wastes type maps. Big giant open boxes sound more fun, but it's certainly easier to craft and place content when you have a more fixed idea of what direction players are going to be going and when they'll come upon whatever is there.
We sure as shit won't be dropped into a Hinterlands type environment first thing that's for damn sure. Even if there are a few planets somewhat like it.
I still haven't played Inquisition but I imagine maps will be a bit wider in Andromeda simply because they'll be designed around vehicles rather than on-foot travel.
Massive landscapes don't automatically have to be bloated with content.
