Perhaps they are going to do The Secret Story format that started in France.
This is the wikipedia entry about it:-
Quote:
The contestants are kept locked away for 14 weeks in a house, called "La Maison des Secrets" (the House of Secrets) measuring 1600m² styled on the UK Big Brother house including a swimming pool, jacuzzi, a lounge, a big bedroom divided by a shattered glass, bathroom with showers and 5 secrets room which are the Crystal room, Love Cave, Museum of Secrets, White Room and Bedsit (like Big Brother 5 UK). All of the rooms are installed with cameras, (except the toilet due to a law imposed by the Conseil Supérieur de l'audiovisuel). The Voice speaks to the contestants at times, and acts like "Big Brother" in other countries. Each contestant has to conceal a secret which the other contestants must try to discover. If a contestant does, that contestant wins the jackpot of the contestant whose secret they have guessed. Each secret is worth €10,000. Each Tuesday, 2 contestants are nominated and put up against the public vote, one housemate will be evicted every Friday. Housemates are only permitted to nominate every other week and housemates are only allowed to nominate other housemates of the opposite sex.
