I've no idea what channel Taskmaster will end up on but, whichever it is, I really hope it retains pretty much the same format: with the same hosts and similar types of guests (i.e. mainly comedians and not reality or soap stars). Provided it does, then I really don't mind which channel it's on.
Remember it'll be the same company and the same team making the show wherever it ends up. Avalon produce it, and Alex Horne and Greg Davies are managed by them. They won't change and neither should the style of the show, Alex is exec producer and its very much his vision
