at least 2, if the game sells well, they will create them. And what's so bad about that? At least all these races will be well-balanced, and it will also be easier to tell the story (I mean the events 400 years before Heroes 5).
The more races, the better. Variety. In "Heroes 5", they easily created six excellent campaigns with an interesting plot for each of the races. What's wrong with "Heroes 6"? And if the developers don't bring back at least seven races from "Heroes 5", the fans will tear them apart :):p!
