Yeah I'll be very surprised if the show doesn't go on hiatus again
there's a lot of pre-production and filming involved in Takeaway (that this series had less of given Ant's issues last year) and if he's not going to be back for even IAC I don't see how that can go ahead
Personally I'd prefer them to quit BGT going forward because it's the show that needs them the least and then they can focus on this more but I can't see that happening tbh
