Never really got into the character folios. Never understand the need. Pay $10 for a product that gets wasted as soon as your character does.
Anyway, You also forgot to mention that we get Rogue Trader at the end of next summer. Its not Dark Heresey, per se, but it is 40KRPG. Jan/Feb is Creatures Anathema, so another DH book in the Spring and Summer just before Rogue Trader wouldnt surprise me.
It all depends on sales, it has to be worth FFG making new books in order for them to dojust that. Ill be honest, Im a big proponent of supportng BI/FFG/DH/40KRPG. Moreso then WFRP which I also love.
To prove my love nad faith in the system/setting/game/company I used Dark Heresy as my X-Mas gift to most of my gamer friends (the ones I really like that is, a few back home in Ohio and a few at Fort Meade) just to ensure that A) they play a game worth while and I approve of (Im one step away from putting my friends in a RPG Police State ruled by me) and B) to support FFG.
The hope is that they like the game and play it and that they buy the rest of the stuff themselves.
Ross gave my buddy Brien a free hardcover copy of the IHB at HeroCon and Brien then bought the GM Screen, PTU and preordered DotDG that very night.
Request your players get their own copy of the core rules (dont force them to do so however, just kindly suggest). You will be amazed at how fast we could get the # of books sold doubled. Specialty books like DotDG and CA are less likely to sel in large numbers, as players wouldbe like "nah, dont need that, I just play in the game". So some books have to be universal in appearance. New world origins, weapons, gear, careers, player options would be decent sellers.
That is why originally BI was going to release the IHB and the Inquisitor's Armoury as separate books before putting them together in one book. As two books they would be able to charge $25 each for a net of $50, but I suspect decided to merge them into 1 when they decided to close shop.
