No-one's absolutely sure, bananarama - however the following is an extract from the transcript that Honey posted up of the conversation between Dermot and the senior producer (Phil):
Dermot - Finally...the BIG ONE!!! Are the Bars a permanent fixture?
Phil - Oh NO NO NO!!!! They were always meant to do a specific job in the middle of the series, but they'll be in for another week. ........
(then they talk about the most recent musical chairs task)
........... And then the following week we're going to give the housemates the
chance to bring the house together as one and lift the bars completely through the task. So watch this space because that will happening that week!
So your guess is as good as mine! Let's hope the housemates pass this week's task and then it'll be 'bye bye bars'!
