Having read this excerpt, I'm quite thrilled at Complete Divine. If I hadn't planned on buying it anyway, I'd be resolved on picking it up after that article!
The fact that they're dusting off some older stuff is nice. I know it can seem annoying to be buying the same material again, but I'm glad they're consolidating a significant amount of it in one place.
The sections on "fluff" seem almost worth their weight in gold. That except from chapter 6 was something I've wanting to see for a while now. Finally we're getting the dynamics of how things world in a fantastic world! There are great role-playing possibilities with things like knowing that the soul remains where the body died for a few seconds, or that some undead can perceive the memories of the spawn they create.
Finally, I'm jazzed that they're giving the nod to more of the old Greyhawk deities. I'm always in favor of updating material from previous editions, and them giving new info on the old GH gods is more than welcome. The only thing I'm miffed about is that the domain listings are split between "Core deities" and "Other deities", that seems unnecessarily derogative to those other GH gods...it's not like the group in the PHB are in any way better, stronger, or more distinctive.
