This caught my eye earlier, perhaps because it involves dimension-hopping flying ships. It's a Russian MMO that is perhaps best described as being something like "World Of Fantasy Naval Combat On The Astral Plane". Allods Online is a fantasy MMO in which players adventure in the astral, and take up arms for two factions which are duking it out in giant magical galleons. Between, presumably, bouts of grinding mobs of astral demons that are kicking about in the various locations you can travel between. The two trailers below introduce the game idea and show some of the ship-to-ship combat that players will be getting involved in. Intriguing stuff.

Here's a bunch of images of the ships:
