Most years have had a focal twist/event for the series:
-BB3: Rich and poor
-BB4: Swap with African BB
-BB5: Bedsit
-BB6: Secret garden
-BB7: House next door
-BB8: Halfway house
-BB9: Heaven and hell
-BB10: Can't remember anything of significance happening... birthday week? with past housemates
Wonder what this year's big thing will be?
Do you reckon there'll be another house in some form?
