CCP and White Wolf "merged" back in 2006, over 3 years ago. At the time it was announced that they'd already started working on a WoD MMO. As to which of the supernatural creatures will be playable, who knows, information has been extremely limited.
Interesting to note that Mark Rein·Hagen, one of the founders of White Wolf and the main creator of the original World of Darkness stuff lives in Georgia. He sold his part of WW a couple of years ago. Haven't seen any stuff out from him in a while.
