The thing with Air is that, barring the music, there's F A 'oasis' theme at all.
Agreed. I've only ever heard of the "Oasis Theme" on here. Watching the advert kinda suggests peace and tranquility. Maybe Utopia is a more accurate description.
Air does seem to have a bit of an identity crisis. Its themeing is, if anything, closer to X-Sector than FV. As others have mentioned, hopefully if SW7 does go ahead in the Air Carpark AT will be forced to do something with it.
Otherwise I don't see ANY hope of rocks, waterfalls, lights or anything. Hell, if they're not even going to paint it (you can get paint that works underwater so that's no excuse) I don't see any hope of elaborate themeing - although any of the above would be nice.
