It's been touched upon in other threads but as of right now there is no clear indication as to what will happen to Condor Flats leading up to the opening of Carsland in 2012.
Condor Flats is a bit of a hodge podge of avation history. Upon entering you are greeted with an early 1950's jet fighter. In front of Soarin lies a modern rocket engine. Soarin' itself is a hang-glider flight over modern CA. Towards the back of Condor Flats you'll find an old Army trailer and another semi modern plane. So in theory the only real "theme" to Condor Flats is the desert itself. The main question is will it remain a desert sub-land when Carsland opens? Condor flats was initially designed to represent the deserts of California but Carsland will be able to display this landscape on a much larger scale. Carsland will have intricate rockwork and highly detailed desert themes. So what is to become of DCA's original desert? If it becomes the forest then the aviation is even more out of place. The reason the desert was full of runways is because it's flat and has minimal obstructions. Forests by definition are full of trees and at times hilly, not exactly ideal for runways (can be built but generally avoided)... so what do all of you think Disney will do? Will they have 2 desert themed areas? Will they combine what was Condor Flats into Carsland (which I don't believe is possible given the requirement that Carsland be only Cars based)? Will it be an expansion of the forest?... Hopefully those in WDI thought about this because it is an interesting question.
