Microsoft's Windows 10 operating system-powered high-end smartphone will be available in the summer, suggests a new report.

While Windows Phone users are eagerly waiting for first Windows 10 Technical Preview for phones, which will be released in later February, the latest report on the launch on the Windows 10 flagship smartphones has set rumour mills on fire.

New Lumia smartphones

According to anonymous sources quoted by Chinese website WPDang (translated) the Redmond-headquartered company will announce two new Lumia smartphones at the 2015 Mobile World Congress scheduled to be held in the first week of March in Barcelona. The smartphones would reportedly aim the mid-range and entry-level market segments.

One of the smartphones is expected to be the Lumia 1330, which could be the successor to Lumia 1320, and the other one could be a cheaper variant of the Lumia 830, with a PureView camera and less storage capacity.

The sources claimed that Microsoft's flagship smartphone powered with Windows 10 operating system would be launched in May-June.

Recently, Ifi Majid, director of product marketing for Microsoft Mobile Devices confirmed that the flagship smartphone is likely to be launched "later this summer", which could be in line with the latest disclosure.

Besides, Microsoft's BUILD developer conference will be held from 29 April to 1 May, and the new flagship smartphone is expected around the same time.
