Fiend Folio does not start new series of books

[GBDeluxe]

The main page mentions that the covers revealed of Arms & Equipment, Savage Specieds, Races of Faerun, and Fiend Folio, reveal something about the content / style of the book. But Fiend Folio is not a new style - look at it again. That is the style of the Book of Vile Darkness. Fiend Folio will be the second in the "Mature" line of products.

Eh- not quite.

"There is specific information on how to integrate these monsters easily into a campaign of any level, in addition to new abilities, magic items, and spells."


EDIT: That's also not the actual cover. Its a mock-up or so I have heard.

Well, I hope that artwork gets used somewhere, it's pretty nice!

Color plate in the book itself perhaps? Even a jpg online, that is just a really cool piture, shame to let it go to waste.
