The site's source claims Microsoft is finalizing the feature set of Windows 10 Creators Update:
Microsoft is currently in the process of finalizing things for the Windows 10 Creators Update. The Creators Update is expected to be “feature locked” by mid/late January which means most of the shipping features will be present by that period. That certainly doesn’t mean that the update is “complete” per se, as Microsoft will be working on polishing the new features and fixing bugs before the release.Furthermore, Microsoft is also working on the next big update, which is expected towards the end of this year. Codenamed "Redstone 3", this build is expected to introduce an improved design language for Windows 10.
