The Barsoom stories were a big influence on the development of Dark Sun, so this is likely the closest thing to a DS movie we're going to get for a while

I agree with the OP. The trailer does seem to exhibit the dying-world environment and melancholy feel of both Athas and Barsoom. As a fan of both, I am keeping my hopes up regarding the quality of the movie, and I look forward to future trailers. The airships look cool.
