I was assuming they would redo the catwalk lighting to match how Studio D has looked since its revamp (i.e. bottom lightbox is red and top is white), but it seems to be the same as it always has been.

Those LED light boxes have always been able to be any colour they wish. It's just that when they're turned off they look brown. At least it looks as though there is a curved LED wall replacing the large plasma screens.

Unless they were going to strip everything back to bare bones, and even reposition the Furio tracks, then they're fairly limited in what changes they can make. It's essentially a set designed around a circle, which other than Studio C, conflicts with everything else they're using domestically and in the US.
