LOST will return Tuesdays at 9pm starting February 2, 2010. I'm not sure yet what this means for the 8pm and 10pm schedule (though the betting seems to be on V taking the Tuesday 10pm slot after the Olympics) or what will happen oncereturns in March, but sooner or later (hopefully sooner) ABC will reveal its mid-season plans and we'll update you.
The Groundhog Day return will feature 3 hours of Lost - a one hour recap plus a two hour premiere.
Update: Here's the press release from ABC:
