Hi there!
It's more or less as has been posted already, regarding an Age of Worms hardcover. WotC owns the rights to everything that appears in Dungeon, and that includes the reprint rights. Before we can go ahead with an AoW hardcover (which I'd love to do, since magazines don't get reprinted and once one of the 12 parts goes out of print... poof! the campaign's got a hole in it for future players), we need to get permission from WotC to do so.
So far, we've not been given the go ahead on the project.
There's no reason to suspect it'll be any different for Savage Tide, so anyone who's interested in running the new Adventure Path in Dungeon should consider picking up the issues as they come out.
For those who have Age of Worms already... the good news is that there's not much needing adjustment to it really. Shackled City had a fair amount of warts (3.0 rules at the start, us not knowing how to pace adventures, us having to cut large parts of adventures, etc.) that compiling into a Hardcover version let us fix. There aren't as many for Age of Worms. Having it in hardcover merely makes it easier to transport. I suppose if/when we DO it up as a hardcover, we'll shore up some of the minor problems and will likely expand upon it here and there... sort of like the extended "Lord of the Rings" movies did.
But for now, the magazines remain the only place to get an Age of Worms fix.
