It won't air next year - they've just announced it not to frighten off advertisers for this series and added Uncut to get a bit of attention for their "sexy single" season, knowing the two aren't linked.
And Seven don't have the goodwill behind them to do a live season and make a success of it.
Totally agree. Why would they commit to another season before the existing train wreck has yet to air, and with no house to shoot it in, it makes zero sense. It's all just a publicity stunt.
