Trying to put aside that I think Simons completely lost the plot. I personally think it would have made much more sense to put X-Factor: The Band on first with the more spread out episodes, I get the impression celebs going to be a drag and The Band version is going to be rushed through and chaotic. I'm expecting some dodgy production once we get to Birmingham!
I suspect this band X Factor, is to try and upset the Little Mix one there doing on the BBC and was a last-minute decision. All this drivel Simon comes out with to the press about having the 'idea first' and were 'always going to do it' just makes the whole thing look more desperate...
Also on another note, why do we need The X Factor branding on everything? He should have just done his La Banda format, I think Simon is part of the problem (he does AGT, BGT still and their spin-offs) just realise The X Factor brand is tarnished! Try a new format (La banda has done quite well in some countries) and let some new fresh judges have a go. You might not be a judge any more on the show but at least if La Banda was a success in the UK, it's still 'simons' format - rather than risking The Masked Singer taking it's a spot (if that goes down well).
Also on my final note, by doing all these versions of The X Factor and you got The Voice; they're taking away the excitement for The Masked Signer? No one is going to be able to stomach more singing in the space of 1 year. Have ITV thought about that?
