Now we don't know if this game will actually be called StarCraft 3, or even be an RTS at all. I think the most likely outcome is a new StarCraft RTS, but not called StarCraft 3.
Apparently there was an intense bidding war between Korean companies for this, so I don't think it's going to be some small thing. I really think the love that Korea has for StarCraft will make this something that won't disappoint (at least less than SC2 did)
