In fact, all the settlements looked pretty big -- the town with the escaped convicts looked well populated, and Nipton was very big, too. Nothing actually seemed cramped from what I saw of the desert, it's just all the villages are much bigger, so that might make the Mojave feel smaller.
Personally, I prefer more and bigger settlements over a large desert. Really, it's been 200+ years since the bombs fell, isn't it time we get a few bigger towns up and running?
I agree, I mean, I'm sure the desert itself will still be reasonably large, and it will still be there to explore. And besides the desert, we will get a lot of awesome settlements with cool people to talk to. I'm not worried about the size at all at this point.
