A couple of weeks ago a member posted how Ian Royce (BGT, X Factor Warm Up) tweeted:
You want to know what happened with @SimonCowell @bgt in the autumn @itv
The member was saying how BGT could air in the autumn, meaning that X Factor wouldn't be on this year so that Simon could come to panel in the 2014 series which would air early in the year.
I emailed Ian about this and here's his reply: Sorry, man brain!
He subjected his reply as "It's the Spring!"
So looks like we will have an X Factor and BGT will be in the Spring like always

Just thought I'd let you know to stop any confusion.
