Interesting. Somewhat unexpected, though it does perhaps explain why WW was a little odd about handling the oWoD. Given the time and money they've invested in the nWoD - and the fact that it would be easier to adapt into a game setting imho - its a bit surprising. But I suppose that the oWoD has more name recognition.
A couple other factors to keep in mind...
I would argue that the oWoD doesn't necessarily have more depth, but it has more flavor. They had nearly a dozen years to expand on almost every creature, splat and NPC over the course of decade long metaplot development. Sure, there are lots of interesting NPCs and splats in the nWoD, BUT the model has always been to avoid mentioning things in other books. Some get a little more love (like the Morbus and Khaibit, for example) but most bloodlines, lodges and the like are never mentioned again.
Likewise, WW pretty much has a clean slate to work with. There are plenty of cities that weren't covered or were mentioned only in passing in the oWoD. Perhaps we will get something like Atlanta or New York, and WW can play with the metaplot to make the setting different. Keep it contested between Camarilla and Sababt so that players have lots of missions to run. They won't have to worry about some big secret or development being contradicted in a later setting book. nWoD and oWoD remain as separate entities.
I'm very curious to see how this will turn out. I suspect that it will only be BASED on V:tM and the oWoD. Perhaps they will change and get rid of (or ADD) certain things. I think that we will see most of the same Clans, Camarilla and Sabbat, Disciplines, and the like, but we might not get Paths of Enlightenment, Thaumaturgy or certain bloodlines. Or if we do perhaps they will be significantly altered to fit the setting. It's hard to say.
The Camarilla-Sabbat divide makes sense. As mentioned WoW has the Alliance and Horde. EVE Online has four respective factions. Presumably the V:tM MMO would take the same approach, and players would choose whether they wanted to be Camarilla or Sabbat. The choice of sect would allow different missions and character options. Quite frankly, I've never really liked the approach that ALL character options should be open to everyone. If you want Vicissitude, then pick Sabbat. Somethings SHOULD be Clan or Sect exclusive imho.
If we see this, I suspect that the Camarilla will have to get some new stuff just to level the playing field. One of the problems in the oWoD was that the Sabbat had waaay more diversity than the Camarilla, thanks to all the antitribu and weird bloodlines (often with their own unique Disciplines). It made the Sabbat seem more 'kewl' to a certain subset of players and led to all kinds of bad stereotypes. Perhaps the Camarilla will get some new Clans or bloolines, or they will keep Thaumaturgy (which was really a nasty advantage the sect had over the Sabbat) and make it more versatile and dangerous.
As I said before, I suspect that some of the Clans will be cut or heavily modified, if only because their nature and powers don't mesh well with video games. Supernatural strength (Potence), speed (Celerity) and resilience (Fortitude) are all pretty straight forward. Ditto for most applications of Obfuscate, Protean, Auspex, Obtenebration, Quietus and even most Thaumaturgy Paths and Rituals. Dominate, Presence and Dementation strike me as MUCH more difficult. Maybe they have certain affects on NPCs, as well as a few special attacks for other situations.
Then you have powers like Vicissitude and Chimerstry which, quite frankly, strike me as nearly impossible to adapt for an MMO. Sure, the higher levels of Vicissitude are pretty straight forward, but how do you represent changing your appearance or creating illusions? WAAAY too broad. My guess would be that the powers would be tweaked to a certain progression of pre-selected illusions or appearances. Vicissitude might take some powers closer to the Molitate Arcanos from Wraith. I don't know.
Quite frankly, I would LIKE to see the Independent Clans and certain Bloodlines, but I'm not entirley certain we will. At least, not right away. Still, I'm going to hold out hope. Of course, like I said, some Clans might be up for the chop, and the Independents are far more likely. Perhaps this setting will expand on the Week of Nightmares and make the Ravnos extinct.
One cool thing is that we at least ARE going to get some of the fun elements from the oWoD. Well we probably can't expect EVERYTHING, perhaps we will see references in passing to Carthage, Salout, Gehenna, the War of Princes, the Week of Nightmares, Soul-Eaters, Golconda, and so forth. So much fun stuff.
And, I'm holding out hope that perhaps down the road we will get more expansions. Perhaps we shall see a Werewolf: the Apocalypse expansion, a Mage: the Ascension expansion (hard to do, but possible), and so forth. I don't know if we will ever get as far as a Mummy expansion, though it would be cool, but perhaps we will at least get some of the other elements that never fully got explored in the old WoD thanks to the whole Gehenna thing.
Well, thats it for my current thoughts right about now. No doubt more to come as we learn more about the upcoming game release.
