In CC CS6 where do you change the lightness/darkness of the interface?

Sure. It's right there, together with the improved INX export.
"New In InDesign: [..] See the greatest improvements in speed and stability when printing and when exporting PDF and INX files."

Because InDesign needs to change file format when there's a major change, we may need to refer to the new version as InDesign 9.0. But there may be minor changes and updates which won't require a new file format available for download at intervals.
