The Sacramento Bee (Mary Lynne Vellinga) reports:  The NBA’s urgent effort to get a new arena for the Kings built at Cal Expo has gone into slow motion because of the sputtering real estate economy. “There’s no lending out there right now, so real estate development is absolutely flat,” said NBA point person John Moag. Moag said this week that the NBA and Cal Expo likely will push forward with planning for a mixed-use project at the fairgrounds that would include an arena and a revamped venue for the State Fair. The two parties expect to seek proposals from developers in March, he said.
