My prediction is it will be something Ghost related. They will never make an MMO that is medieval based to only compete with WoW. They've already stated that they would never cannibalize WoWs sub base. So, my bet is on something with a futuristic, and/or sci-fi setting. Starcraft would be difficult since a lot of those units would be limited in what they offered. But I have seen an early build for Ghost, which was halted indefinitely, and there is definitely a game in there somewhere. It was a 3rd person sci-fi shooter.
