After Microsoft’s acquisition of Skype in 2011 for $8.5 Billion it’s understandable to think that they’d want to use the service for as many different applications as they can.
Queue Xbox Live, a recent job vacancy advertising the position of a user interface designer with the working location being listed as Microsoft’s Skype offices in the UK has sparked the belief that it’s only a matter of time before we see Skype on the Xbox.
We then have additional statements from a person “who is familiar with the matter” who has stated that Microsoft are planning on "consolidating all their communications technology” presumably around the Skype platform.
The source then went onto say “You might jump to the conclusion that we'll see asynchronous voice and video messages in next-gen Xbox Live” which means we’re ticking all of the boxes once again for Skype.
However there’s currently no official statement from Microsoft, it’s safe to assume that it’s perfectly feasible given the disappearance of Windows Live Messenger in place of Skype.
