I'll echo the suggestion of the War of the Burning Sky. I'm running it for my online group, and we've been having a good time. We're early in the third adventure right now, and I'm excited to get started again after our recent holiday break. As with any published adventure, I strongly recommend that the DM customize it as much as they wish - I made some big changes in some areas and small tweaks in others, all for the better in my opinion. It's a great campaign, and it gives the DM (and players) a good amount of freedom.
I'm also lucky enough to be involved in a storyline play test for ZEITGEIST, and while I'm not allowed to talk about it yet, I can say that I really like what I've seen so far. I expect that it's going to be a very cool campaign when it comes out, whenever that may be (I honestly don't know anything about the timing of the release of the campaign itself).
