*Oppose - So how do we define the time when it is being "officially" being pushed out? Microsoft has officially announced the rebranding of Windows Live ID to Microsoft account. (Ref: ) As you mentioned, some products (such as Windows 8 and Visual Studio 2012) already refers to it as Microsoft account. Some service will gradually transition to the new name. Whilst some other products may never transition (do we really expect Microsoft to update mentions of "Windows Live ID" in Windows 7?). There will never be a fine line to say "yes, Microsoft account has been officially pushed out" today. In such case, I believe that the official announcement is sufficient. Furthermore, Windows Live ID already redirects to Microsoft account, and hence readers will have no issue reaching here.
