With the rumors going around of FFG working on an LCG based on the World of Darkness with different factions such as Vampires, Werewolves, Mages and Hunters, I am VERY excited!!
Here's the thing, though. As far as I can tell, the only evidence for these rumors are a couple of threads on 4chan, from people who allegedly attended playtesting sessions. Since these posters were anonymous, they could've all just been one troll making up the whole thing out of thin air, and then replying to themselves.
Here's a link to an archive of one of threads.
For one thing, obviously people are violating NDAs. Somebody's been talking about Fight Club. More than one person, if you believe that thread. However, I was part of the Netrunner playtesting group, and it was done entirely differently. It wasn't held at an FFG Event Center, it was all online. (PDFs distributed, printed out, and sleeved, etc.) I figured that with the success of Netrunner, any further LCG playtests would probably be done in a similar manner. Maybe they're doing it in a more controlled environment, because they're worried about leaks? (Which is funny, because Netrunner didn't have any leaks, and this one has had a HUGE one!)
However, if I had to bet, I'd say this is a hoax. There is currently zero evidence for it.
