Yeah, I've seen some of the maps of the DHS version and they don't have nearly as much space to work with there to transition Star Wars into the rest of the park. It's going to be abrupt. Which is weird and ironic; yet another WDW park that seems strapped for space and land.
At Disneyland, all this new eye candy will dramatically improve the giant walls of overgrown trees and shrubs that have defined the back half of Frontierland for decades. All the new cliffs and waterfalls along the Rivers of America, the trestles and rocky ledges along the Disneyland Railroad trackbed, the cavern entrances into Star Wars Land, etc., etc.
It will be a dramatic theme improvement over
The Great Boring Wall of Green that defined this third of the park for the past 30 years (since they shut down Nature's Wonderland in '77), where a few fiberglass animals frozen in place, a peek-a-boo look at the parking structure, and that rickety Indian Chief were big highlights.
