> Additionally, how is Battlenet 2.0 going to "connect" Starcraft 2 to World Of Warcraft? How does your Starcraft 2 rank matter, at all, in World Of Warcraft? This is a genuine question, since I haven't played either game.

The only tie-in I've heard of deals with SC2 Collectors Edition. Purchasing it gives you a rare "Mini-Thor" pet in World of Warcraft.
