I'm not really sure what's coming out, to be honest with you. Complete Scoundrel looks like it'll probably be interesting. Monsternomicon v. 2, if it actually comes out in 2007, is certainly what I'm looking forward to the most, and have been for years. Dungeonscape looks potentially interesting, and I've enjoyed the other environment books so far, so they have a decent track record.
Not sure about Star Wars--if it more closely mimics the system in KoToR, and provides some more info on facilitating gameplay in that era, that'd rock. Otherwise, I've already got two versions of d20 Star Wars that I don't use as is--do I really need another?
