FR / GH / DL Compendium

Assuming that the new Dragon Compendium takes off (I'll definitely be getting a copy) would Paizo ever consider doing the same thing but for the various specific gameworlds that only they are licenced to show material of. Of course, I'm talking about the Realms, Greyhawk, DL et. al.

All the various FR articles, updated for 3.5E (where necessary), and collected into a hardcover would make me drool.

Just a thought.
