According to
THIS ANANOVA ARTICLE Endemol are considering running the fifth series of BB in Germany for
A WHOLE YEAR!!! 
Now as much as I like BB this seems completely ridiculous to me, for a start how could they expect the housemates to take a whole year out of their lives to live on a tv show, and what would it do to them psychologically being cooped up in the house with no outside contact for so long.
Another point is would we actually all watch it for a whole year, wouldn't we get bored with it after a while - we certainly would if it was as exciting as BB4
and I think if I had had to put up with BB3 for a whole year I would have ended up suicidal
I think we would have even got bored with BB2 after all this time
What do you all think?
