As for Orcus, he'll be detailed since he IS open content, due to the fact that he's statted up in Necromancer's "Tome of Horrors" and, more importantly, because he's a mythological entity from the real world.
We're not going to illustrate all 32 or so demon lords; the way the book'll be set up will have two demon lords on the left hand page and one on the right. The one on the right will have about 100 to 150 more words of detail AND will have an illustration. Orcus happens to fall on a left hand page so he'll get no illustration and only have a single column of info.
Sadness. When I first saw the pictures I thought that the one for Angazhan might be the Paizo take on Orcus. I hope you don't mind if I appropriate him for such a purpose in my home game.
