Simple but nice, though we'd have hated it if it was for Christmas. A few shows in the trailer I'd not heard about too - I guess The Big Painting Challenge is the latest attempt to rework the Bake Off format.
So did the Love 2014 one though. I doubt they'd have gone back to filmed Christmas idents if they were planning to dump the concept a few weeks later for graphical idents - though as this is the BBC stranger things have happened.
Must say though it's more British Gas than BBC One!
