ABC announced a new strike-affected midseason schedule on Friday. The most prominent change is the return of Lost on January 31, a Thursday. The show will air at 9:00 p.m., the time period ordinarily occupied by the network's biggest hit on that night, Grey's Anatomy. The problem that the network faces is that while it has eight new episodes of Lost ready to roll, it has only one episode of Anatomy -- thus, the decision to move Lost from its usual Wednesday time period. ABC also announced plans to premiere its drama Cashmere Mafia on Thursday, Jan. 3, before moving the show to Wednesdays at 10:00 p.m. Only eight episodes were completed before the strike.
