Not forgetting that Celebrity BB starts tonight, I reckon when that ends Desperate Housewives will fill the slot, started about the same time last year.
From what I've heard from a friend who has a friend who is working for channel 4 I heard it is to be Desperate Housewives, then come end of May it will be BB7 then when then finished in the Autumn it will be Lost season 2 though I'm myself dubious...
there starting this new show on sunday which looks like it coul take over the timeslot and is another usa show called Invasion. The pilot is on channel 4 at 8.30pm and then they show celeb bb and put the second episode on channel 4 at 10.00 pm and they're doing the same as lost and E4 has the third episode on their "first look" thing at 11pm - that same episode is repeated on Wednesday night on E4 at 9pm. It apparently has had rave reviews in the states and is a SCI-FI show - the first episodes are about a hurricane ripping apart central america which was shot before hurricane Katrina and the networks almost made them ditch the whole series afterwards but they ran with it anyway
