"Lost": More fish-biscuit crumbs on ABC.com

ABC.com has more fish biscuit crumbs for "Lost" freaks. There's a short trailer for season 4, now that it's been skedded for Jan. 31.

But the better new item is a roughly two-minute vid with Damon Lindelof and Carlton Cuse that teases some of the story threads that we'll be picking up at the start of season 4. Top of that list seems to be a return to the mystery of Michael, now that Harold Perrineau's back for a recurring role, and his departure, after grave treachery, with Walt on that boat at the end of season 2.
