It appears Microsoft is working to end its Lumia series. According to an employee at the company, who wishes to remain anonymous, the company is preparing to “end sales” of the lumia smartphones December 2016.
According to WinBeta
, which first broke the news, the source says that the Lumia brand will be totally removed from sale by the end of the year, rather than just having production ceased. The speculation is that this will make space for the rumoured Surface phone
, a notion corroborated by a pair of now-deleted tweets sent by one of Microsoft's engineering directors, Laura Butler, who wrote"Surface iPhone. ;-)" on September 6, and "Surface Phone not NOT confirmed. :-)" on September 7, in reply to questions.
Microsoft is holding an event in October to announce a Surface all-in-one, which is when the phone could be revealed as well, or it might be held back for an event in 2017.
