I feel that Skylight already got an "update" and that was Tungsten. That was the move to a modern, flat, dark interface. It took a little getting used to but I decided I liked it better than Mercury and that's what I use now. Please don't change anything, it's perfect.
Sometimes in the past Cakewalk went backwards with their interfaces -- for example, going from Sonar 3's beautiful blue scheme to Sonar 4 and 5's gray was int he wrong direction; thankfully, the colors could be fixed easily. But then Sonar 6-8 was so horribly ugly I boycotted upgrading until Cakewalk gave me a special deal for 8.5 ahead of the X1 release, which was when Cakewalk finally got it right again.
