Diablo 3 fourth class soon?

With BlizzCon ‘09 coming next month, you don’t have to be a genius to tell that Blizzard will have to make some kind of Diablo 3 announcement.

My count of the rumors regarding the fourth class can be boiled down to two:

Ranged character – the parallel is to the rogue in the Diablo I and the Amazon in Diablo 2
Knight – similar to the Warrior in Diablo and the Paladin in Diablo 2

Believe it or not, there’s speculation that the Knight is out of the question for Diablo 3 and that Blizzard would like to introduce a truly unique character, like … a Vampire!

I think it will be ranged character, could be called Ranger or Hunter. A pet is NOT out of the question, though that could be my WoW Hunter talking!
