Can Heroes 6 fail in sales?

With such an information policy, it's easy to happen! They removed everything old, and there's nothing to attract old fans, while the new content isn't being highlighted, and no one will buy a "pig in a poke." Everyone will just download the game to satisfy their curiosity! For example, pre-orders could already be available, but who would place one if, two months before the release, not all factions are known, and I'm not even talking about the mechanics and balance!
