A World Of Darkness MMORPG is either currrently, or soon to be, in development by Crowd Crontol Productions, who acquired White Wolf. CCP has one MMO on the market, EVE Online. By all accounts it is the least MMO-like MMO on the market. It's almost entirely based on skills rather than combat.
It sounds promising. Keep in mind though, it will most likely be based on the new World of Darkness and not the old.
And they never specifically say Vampire or Werewolf MMO - it's always been referred to as a World Of Darkness MMO, which leads me to believe all WOD games will be included in the MMO.
On the other hand, White Wolf will be making a table top version of EVE Online.
