Update: Confirmed - V Returns March 30 and will air at 10pm after Lost.
Wow, my DVR's flash forward was even more prescient than I thought! East coast viewers report that a promo ran during the show that said FlashForward wouldn't be back until March.
TVMoeJoe has more details (though not many more, pretty much just the predictable "let's get this maimed show out of the way of the Olympic onslaught," even if that doesn't explain why it wouldn't air in January!).
This, and OK, the date, convinces me we will not have to wait very much longer at all for the full announcement of ABC's mid-season schedule.
