Microsoft Is Rumored To Be Working On A Surface Phone

According to Windows Central, Microsoft is moving forwards with plans to develop a new smartphone  being referred to as the "Surface Phone." Hardware specifics regarding the phone are unknown at the moment, with the report saying Microsoft is "currently exploring different technologies." Intel is said to still be involved with the project, and it may have an Intel x86 processor chipset. Does this mean the end of the Lumia phones ? I see this as a way of Microsoft to expand the Surface across there devices. What do you think ?
