Microsoft was reportedly planning to release three additional Windows devices on top of the always rumored Lumia 950 and 950 XL. This smartphone trio was the subject of a recent leak that revealed their respective specs. However, an update to this news is that these handsets will no longer be released. 

According to Windows Central, the alleged Microsoft Lumia 550, Lumia 750, and Lumia 850, all tipped by @evleaks as codenamed Honjo, Saana and Guilin, will not see the light of day. All three were allegedly slated to be released alongside the Lumia 950 units.

On the word of WM Power User, the handsets are still being used by Lumia as testers for the Redmond-based tech giant's newest software, Windows 10, which will be launche on July 29. It looks like they were only meant to aid Microsoft in perfecting the mobile version of its newest operating system. 

The three handsets are all mid-rangers but the most powerful among them has to be the Lumia 850. They all come with a 5-inch screen but Lumia 550's is only at quad HD, the Lumia 750's display is at 720 pixels, and the Lumia 850 at 758 pixels. 

The first two have 8 GB inbuilt storage but the third one has double that amount. All of them, however, offer 1 GB RAM. The Lumia 550 has a Snapdragon 210 chip while the Lumia 750 and 850 rely on the Snapdragon 410 SoC. Notably though, the former is clocked at 1.2 GHz, the latter at 1.4 GHz. 

The Lumia 550 has a 5 MP AF rear camera and a 2 MP front shooter as well as a 1,905 mAh battery. The Lumia 750 boasts a bigger 8 MP primary camera with Zeiss optics, a 5 MP front-facing camera, and a 2,650 mAh battery. The Lumia 850 has the same battery unit but has a 10 MP rear snapper and a 5 MP camera on the front. 

According to Softpedia, Microsoft has one device left that is still likely to be released. It goes by the alias Saimaa and is said to serve as an entry to the Lumia 6xx lineup.
