Sorry if this as been asked and answered before (I tried looking, but didn't find), but are the Player's Guide and Creature Vault going to be published in PDF? The GM Guide is, along with the Liber Mutatis (which I understand is missing from those rules guides).

Presumably, yes.

However, I'd expect the Creature Guide to be next, and then the Player's Guide last of all - perhaps even months from now.

FFG tends to delay the release of the PDF versions - I assume to mitigate the effects of piracy on the electronic versions.

Understandable but also quite annoying. Well, at least annoying for people like myself who prefer the electronic version.
