I'll have to be the dissenting voice here.
I have a love/hate relationship with the WOD. I love it for what it could be, but hate it for the way that most people play it. WW games tend to be real hit or miss with most folks. Vampire has the potential to be great if you play with people who get away from the pure angst and whining. Mage is one of my favorite games and is a great amout of fun (though I never have looked at the new edition). Both Changeling and Wraith are full of some of the most innovative, wonderful concepts in gaming...but are both virtually unplayable unless you have an amazing Storyteller. Werewolf and the offshoot books (Mummy, Kindred of the East, etc.) all pretty much suck. As did Hunter.
Demon, I'm in love with. It's a great game if you're not easily offended with an interpretation of Christianity that's nowhere near the norm. It manages to combine the themes of each of the other lines without including the crappiness from them. And, though it is WOD, it can easily be seperated from such (unlike the other books). I highly recommend this game.
The Storyteller system is indeed wonky in the probability distribution area, but can be house ruled pretty easily.
As for WW not doing well...that's just not right. Please tell me where you can find their product in bargain bins and I'll be there in a jiffy. Here it's difficult to get your hands on any of their new releases because they sell out so fast. While their older lines are kind of dragging on their new stuff is keeping them on the top of the heap:
Adventure!, the third of the Aeon games has a huge following and is one of the best pulp games ever. Exalted is one of the most popular non-D&D games out there now and is absolutely stunning (if it just weren't for the HUGE dice pools I'd be running it) and if you haven't checked out their Dragon-Blooded book for the line you are missing one out on one of the best books in the last year. Plus, they have Sword and Sorceries studio and Necromancer games...two of the biggest names in D&D 3E publishing.
WW is not going anywhere, I'm afraid.
In fact, there's a new WOD game coming out this summer... Orpheus. Nothing is known about it now and I'll certainly reserve my judgements until it is released.
