Sadly, that doesn't confirm anything. It just allows the producers to remain one step ahead and have a back-up set to go on the off-chance that the show is renewed.2015 housemate hunt details are up!
It looks to me like they're obviously rehearsing for tonight (all the HM's are on stage too) so it would appear that the people on screen in the house are crew setting up the show and organizing camera angles, etc. Travis, Ryan and Skye would be locked inside the bedroom or something.
Sociable bunch aren't they? Half of them are more interested in their phone (probably checking how much they're "trending" on, ironically, social media).
Don't pretend like you wouldn't be too.
