I strongly reject the "nothing left to do" argument as I've said in other places.
And I strongly agree with you there.
I remember Scott Rouse asking around here around the time of 4e's announcement about flavor heavy books that people still wanted to see in 3e. We never saw any of the books that people were mostly often asking or begging to see. Fey, FCIII, Giants, etc.
I would have bent over backwards to help work on a Fiendish Codex III. Really wish they would have made one. Especially now when most of the fiends that would have appeared in that book now don't exist in the core PoL quasi-setting (making their appearance in any settings close to nil given 4e design thus far).
