I can be up for participating in or GMing a OWOD chronicle with little to none metaplot.
V20 is a streamlined version of older editions without metaplot bullshit. You don't need books that are being released as expansions, as it is stand alone and contains all clans, disciplines and bloodlines, but Hunters Hunted 2 is still a neat addition that I recommend buying. There are no crossovers with W20 in V20, really, but there is some mention in HH2 what are advantages and disadvantages of cooperating with Lupines to hunt down vampires. Also no bullshit like Imbued. Some hunters can have Numina, but these are nothing like "Hunters".
As for W20, I must say I like their Changing Breeds expansion. Beast Courts are still there, but now it is mentioned that actually many breeds in Asia don't even participate in it, so you can run Asian campaign without the Courts. Beast Courts with their organized, courtly feel are inferior IMO to Ahadi which are newly forged group of African shapeshifters that want to get the shit done in less organized way, forged in a war against a Simba warlord.
But I still poke fun at it being Werewolf: Weaboo Fightan Magic or Werewolf: Hakuna Matata. Screw that, I always mock the shit out of Werewolf, but like it nevertheless, I think it is being best run not seriously.
Wraith20 will be some time after M20, I guess. It seems the M20 is delayed because of proofreading and other extra works.
