I doubt we'll see improvements before release, but the texture quality on the planets is very much below par, at least in beta (maybe I'm wrong, maybe they will up the textures before release) but i doubt it, my guess is the low textures on the planets are to ensure the game runs well on the XBOX unfortunately.
Like i said recently look how good Alpha looked compared to now, there is a reason for the "removal of fidelity" but FD are very much keeping quiet on the subject.
Also, the stations on planets are a copy-paste of the space stations which seems really cheap (check out the enter hanger scene on Europa)
Hangars being the same is only logical. In the world today, there are standards. Think about your car. Ever traffic worthy vehicle must adhere to the same standards as with other vehicles in their class. So, every parking lot looks bout the same. Doing this in a different way in the game would serve no other real purpose than deter criticisms of laziness such as yours.
