In the past, the VtM Player’s Guide gave additional character options, the independent clans, and some advise on playing Vampire. From the blurb, the Player’s Guide seems to offer advice on how to play all the different styles of Vampire. But what else will be in there?
Personally, I hope for at least one new clan (Ravnos or Tzimisce), maybe the reprints of The Ministry and Banu Haqim. Also, since Oblivion (Lasombra/Hecata clan discipline from Chicago by Night/Cults of Blood) is missing a Predator Type, it would be great to include one. Also, a clarification that Blood Sorcery could be taken by Banu Haqim when the Predator Type offers them would be good.
