The San Francisco Gate has more information on the find:

On Tuesday, Hebrew University archaeology Professor Yosef Garfinkel will present compelling evidence to scholars at Harvard University that he has found the 10th century biblical city of Sha’arayim, Hebrew for “Two Gates.” Garfinkel, who made his startling discovery at the beginning of this month, will also discuss his findings at the American Schools of Oriental Research conference hosted by Boston University on Thursday. Garfinkel believes the city provides evidence that King David ruled a kingdom from his capital of Jerusalem. Some modern scholars have questioned the biblical account of David’s kingdom and even whether he existed. Although it is not clear how the Sha’arayim relates to David, Garfinkel says finding a Judean city along the ancient highway to Jerusalem that appears to have been a fortress on the western border with the Philistines indicates a kingdom with a developed political and military organization that was powerful enough to include a major fortified city.

“There is no question that Yosef Garfinkel has found a unique and interesting site of a type we haven’t had until now,” said Aren Maeir, professor of archaeology at Bar-Ilan University in Ramat Gan who is excavating Goliath’s hometown of Gath nearby. “But we have to wait for more findings and more analysis.”
