I'm actually looking forward to picking up War of the Burning Sky at some point. The adventure synopsis I read sounded very creative and out of the box.
Any of the Paizo APs are good, of course, although I can't vouch for Second Darkness, as I'm playing in it and therefore not reading it.
Red Hand of Doom is good, although not as great as I'd heard. I've only read it, though. It might be better in play.
Something I'm really looking forward to is running an Eberron private detective game using a bunch of the good city adventures from Dungeon Magazine: Mad God's Key, Shut In, Fallen Angel, Chimes at Midnight, Murder in Oakbridge, Steel Shadows, Voyage of the Golden Dragon, Quoth the Raven, And Madness Followed, The Styes, The Weavers, Hell's Heart, Swords of Dragonslake.
