Microsoft is rumored to use the 'Nokia' and 'Lumia' brands instead of using the current 'Surface' branding. According to @evleaks, Microsoft may be moving toward rebranding its Surface tablets as "Lumia" devices. @evleaks also claimed that Microsoft may be negotiating to keep the Nokia brand longer than originally planned so that it can use it for future phones.

crosoft was previously rumored to plan to phase-out Nokia branding through December 31, 2015 for Nokia X Android phones and 10 years for Asha mobile phones.

We have contacted Microsoft for a comment but the possibilities to respond on that are weak.

For sure, the the Nokia and Lumia brands have stronger recognition outside the U.S., and Microsoft is doing better selling Windows Phones outside the U.S. than in the States.
