The only things I know about the new VtR come directly from the 'teasers' on the WW website of late.
To put it bluntly VtR looks like a lemon - reducing the number of clans from 13 (+) to 5, with at least 3 of them being virtually identical with regard to their disciplines, roles, and even down to the clan name (as far as I can tell at the moment anyway), doesn't bode well IMO.
Without a wealth of new content and an amazing setting to make up for this I can't see it doing nearly as well as the previous WoD.
The only bright side I can see is that VtR may be better integrated wrt the rest of the new WoD this time around.
It only just arrived here in the online stores this weekend so I'm awaiting reviews before I'm even going to think about picking up the new one.
Happily though it's sparked a number of very good value sales as online stores try to get rid of old stock.
