Blizzard has yet to announce any definite plans on a release date or how it plans to develop it for the PlayStation -- whether it will give it to a third party developer and publisher (like it did for WarCraft II), or whether StarCraft will be developed by in-house talent. According to Blizzard representatives, "We haven't made any final decisions or announcements."
PSMONline's betting on an announcement three months after the release of the first StarCraft expansion pack.
