The post reads:
Placeholder entry for Skype Central Universal Windows 10 App. The idea is to have a shared blog from which PFE/DSE engineers can update the main landing page of the app to include news, troubleshooting, CU release information, or anything related to Skype for Business. This shared blog feed will be the mechanism from which Windows 10 Live Tiles are updated (notifications in Action Center, Live Tile data update, new article count, etc). This shared blog/feed can be hosted on TechNet or a 3rd party blogging service which complies with RSS 2.0.
Further evidence of the rebranding comes in the form of two icons, as seen at the top of the page The change is anticipated to take effect when Microsoft releases a Universal App for its service. There are also some rumors that this Universal app will not only converge the many iterations of the app across devices, but also the consumer and business offerings into one. Naturally, we will have to wait to see if this plan of consolidation and rebranding comes to fruition
Update: It looks like the renaming isn"t going to happen after all. The author of the blog post reached out to the site that originally broke the story and explained the following:
Regarding this post, Skype Central is a placeholder name for a personal Windows 10 Universal App I am developing that acts as a document/tools/blog aggregator. It has nothing to do with Skype for Business or the Skype Product Group. The entry on TechNet was a test feed to be delivered to the app for feed testing and Live Tile testing. The logo is also unofficial and does not represent any current or future Skype rebranding. Apologies for the confusion.
