Although the WGA strike is all but over, Lost is still going to suffer a series cull.

The Hollywood Reporter say that the current season of Lost will only run a MAXIMUM of 13 episodes, losing at least 8 episodes from it’s original plan of 21.
Eight episodes were already scripted before the strike, with a further five now to be scribed and shot, though it’s not expected that any of the major plotlines planned will be scrapped. They will simply “condense them” into the episodes and it’s unlikely that the missed hours will be added to further seasons. So for those saying Lost moves to slow… I don’t think that will be the case any longer!

It’s also entirely possible that the 13 season run will air without any breaks now that the strike is over.
