1) The Elstree lease has been extended to at least 2010
2) Elstree studios want the show to stay there
3) Endemol also want the show to stay there
4) People were calling for the axe after BB4. BB8 is the BB4 of the evil era. It will return in May with a bang. Trust me. Next year we will have a series to remember that could blow BB3, 5 and 6 out of the water.
A new house would actually help. I really like the Elstree site and as a die hard fan (

) it would never be the same if they moved away, but the show really needs to freshen up and get away from the residential estate in which it is currently in. They need to go back to a secluded environment were noone can shout over the wall.
The twists need to stop. I'm not calling for a back to basics because that doesn't work anymore, but if they are going to continue to do twists they have to stop involving secret housemates, messing with nominations etc. There are a million and one new twists they could do that have never been done before. Because the twists have already been done before, the innocence of the housemates is ruined and it ruins the show.
