I bet over the next few days there will be tweeks with the lighting, there seems to be a few dark spots. Just now when Phil and Holly went over to the comp area, holly was very dark.
In terms of graphics, they are quite good, the only annoying thing is that the 'Live' bug is like GMB's in the 14:9 safe area (I think) while everything else is I'm the 4:3 safe area
A lot of getting used to the new set, the new gallery and lighting tweaks to come over the next few days.
I agree about the logo going into and out of breaks using songs is a bit GMB V1 and could become a little annoying.
It did give the wonderful shot of cutting from a close up to a long shot and then running in causing to Phil moving between the cameras.
