Microsoft (accidentally) reveals Lumia 950, Lumia 950 XL Windows 10 Mobile flagships

If you have been keeping an eye on the Microsoft rumor mill, then you know that the software giant is expected to take the wraps off two Windows 10 Mobile flagships soon. These would be its first premium smartphones since taking over Nokia's phone business, and also the first new high-end Lumias to arrive in one and a half years.

We expect Microsoft to announce both smartphones at its upcoming media event on October 6. However, the team at Microsoft Store UK has decided to jump the gun, having just listed Lumia 950 and Lumia 950 XL on the site.

They did not go all the way, however, only mentioning a couple of the most important specs. There is no mention of price, but we do know what sort of displays and cameras they will offer as well as the storage space they offer. And, naturally, there are official images to accompany the listings.

Lumia 950 is the standard-sized flagship, featuring a 5.2-inch display. The resolution is typical of a high-end smartphone, being 1,440 by 2,560. There will be a 20 MP camera on the back, with Zeiss optics, as well as 32 GB of internal storage and a microSD card slot (there is support for cards of up to 2 TB in size).

Lumia 950 XL is Microsoft's flagship phablet that is meant to rival the likes of Apple's iPhone 6s Plus and Samsung's Galaxy S6 edge Plus. It comes with a 5.7-inch screen, with the same resolution as Lumia 950. The camera and storage specs are the same, based on the listings.

The design seems to be typical of premium Lumias; there are physical buttons on the left side -- for volume, power and camera -- and a round camera hump on the back. They look unspectacular in the photos posted on Microsoft Store UK, but hopefully that impression will change when holding the devices in the hand.
