Microsoft has accidentally listed two new Lumia flagships on its online store. The Lumia 950 and Lumia 950 XL are both listed as unlocked models, with confirmation of some of the leaked specifications. Microsoft lists the Lumia 950 as a 5.2-inch handset with a 20-megapixel camera and 32GB of storage. While the larger Lumia 950 is 5.7 inches with the same camera and storage.

Microsoft is expected to announce both handsets at a special Windows 10 event in New York City next week. Previously leaked photos and specifications of the devices also reveal that Microsoft's new Lumias will support a Continuum feature to turn them into PCs, and Windows Hello to unlock the phones with just your face. Microsoft's Lumia 950 XL is also rumored to include support for the Surface Pen, alongside a new smart cover that has a circular cut out for easy access to notifications. Both devices are expected to include support for USB Type-C and Qi wireless charging.

It's clearly early and embarrassing for Microsoft to spoil its own announcement, but check back at 10AM on October 6th for full live coverage of the company's Windows 10 event from The Verge.
