According to  Chinese-language Economic Daily News (EDN), the two models are expected to come with innovative design and functions as HTC has pushed the theme of the event as "Be Edgier" on its invitation card and launched three teaser videos.

The Desire 10 Pro is aimed at the high-end segment and will feature a 5.1-inch 2k display, Qualcomm Snapdragon 820 CPU and a 12-megapixel main camera with 4GB RAM/32GB ROM. The Desire 10 Lifestyle has a 5.5-inch 720p display, Qualcomm Snapdragon 400 CPU with 2GB RAM/32GB ROM targeting the mid-range segment.

The newspaper claims that the two models are also likely to come with a fingerprint sensor. This will make them the first of HTC's Desire family product to support the technology. Another teaser shows the number 150 inside what looks like a camera lens. This could mean that the smartphone will come with a wide-angle 150 degree camera.

Of course it is all a pre-launch leak, so we don't have many details, although this particular launch has been on the drawing board for months.
