"We do intend to announce a new product at the Worldwide Invitational next month in Korea, and we appreciate the enthusiasm and interest in getting an advance look at what that will be, but players will have to wait until May 19th to find out more. Also, we have a very strong connection with the characters and settings of StarCraft, and we do plan to revisit that universe at some point in the future, but we don't have anything new to announce in that regard at present."

In addition, CVG has been told by "well placed US sources" that a StarCraft MMO is in the works. So there you go, a StarCraft MMO may be coming soon. Or, as is more likely with Blizzard timetables, within the next 5 years.
