Yeah, but it's also true.
Monte said that the archfiends were "somewhere in between" gods and mortals...it's not contradictory to think that, eventually, they could go on to become divine and achieve worshippers and such, just that they don't quite have the divine power yet.
A) I fail to see this as contradictory. I don't remember seeing anything that said that archfiends *can't* be gods, just that the ones in the Book of Vile Darkness *aren't*.
B) FR is different than everyplace else. If Orcus rose to godhood there, whoop-dee-doo-bee-doo-bee-doo. It doesn't mean that anyone (even WotC themselves) is under any sort of agreement to take this as anything other than cannon FOR FR. I mean, after all, it doesn't seem like mortals can often raise to godhood status in GH, and they're doin' it daily in Faerun.
C) I think Wizards is over the whole "appease the people who don't give us money" stage. I seriously doubt if that had any real effect on Monte deciding that the archfiends weren't quite gods. IMHO, there's no reason they *have* to be. I'm pretty sure I'm not the only one who's pretty comfy with divinity being an exclusive right of the divine, or with eternal, unchanging deities. Archfiends don't need to be deities any more than high-ranking celestials do.
