Nokia to reveal 'More Lumia' on day one of Microsoft's Build show

Summary: Nokia looks to be readying new Lumia hardware and/or software on the first day of Microsoft's Build 2014 conference in San Francisco next week.

Nokia looks to be planning to unveil some new Lumia hardware and/or software on the first day of Microsoft's Build 2014 show in San Francisco.

The company is holding a press announcement on April 2 in downtown San Francisco, according to an invitation it sent to press and analysts on March 25. The announcement says 'Join Us for More,' and uses the hashtag #MoreLumia. There also is Windows Phone and Lumia branding on the announcement.

Information has been circulating for a while about possible future Lumia phones expected to debut with Windows Phone 8.1. Those phones include devices codenamed 'Moneypenny,' 'Goldfinger' and 'Martini.' However, the invitation for next week's event uses the same smiley face logo that Nokia uses for Nokia Mix Radio, its streaming music app.

Microsoft is expected to reveal officially more information about Windows Phone 8.1, codenamed 'Blue,' at the Build show next week. Microsoft execs shared some of the planned features for Windows Phone 8.1 at the Mobile World Congress show in late February. Many of the features coming with the new Windows Phone 8.1 operating system are known as a result of leaks of the software development kit Microsoft provided to some select developers in February.

Windows Phone 8.1 will feature a personal digital-assitant rival to Google Now and Siri, codenamed 'Cortana.' It also is expected to include built-in VPN support, updated camera functionality, IE11 and more.

According to Windows Phone Central, Nokia also is working on a firmware update for its devices that will piggyback on Windows Phone 8.1, which supposedly also is codenamed 'Blue.' (Nokia has been using colors as codenames for its firmware updates, as of late. Previous Nokia firmware updates have included 'Amber' and 'Black.')

Microsoft is expected to close on its acquisition of Nokia's handset business by the end of April, rather than the end of March, as the company originally hoped and expected.
