I won't buy it, despite I buy a lot of books actually.
- First, I already have DotF 3.0, so I don't need to buy this one (it's the same for new Xpsi 3.5, as I have psi 3.0 and never used it, I am reluctant to buy the 3.5 version even if it appears much better; in fact I got the GR psychic handbook instead).
- Second: it's all about the Greyhawk default pantheon I guess (Pelor, etc.), so what's the use of such a book if you use a different system of religions, or just a very different pantheon? To me, this idea of pantheons is just so bland and so inept...
