They have been doing Air Bag suspensions in Iceland for quite some time with good success. Keep in mind its not always about articulation there but mostly about floating above the snow pack. Spent 7 years there and saw quite a few unique rigs.

The most unique thing was not the air bag suspension but a steering column setup that would steer based off of GPS input. Once again these are things that you can get away with in Iceland because there are no trees (ha ha ha) to run into.
