I hope it's not the last one this year - Lord Sugar's comments have made it unclear whether that rumour is completely untrue, or whether the decision has been made but not by him. I think there is hope though, because surely if that decision had been made, he would have stated that explicitly? He said, 'If there are no more series' in the tweet... that suggests the decision hasn't been made yet.
I think it is in danger though, it only gets about half the ratings of the adult series. I prefer the Young version to the adult version.
