While HTC is widely expected to officially announce the HTC One M8 Eye at a media event on Oct. 8, an official press image of the 13-megapixel packing M8 Eye has leaked.

Samsung has long been the expert at creating a family of spin-off devices to capitalize on its popular Galaxy S series. The company's Galaxy S4, which went on sale in April 2013, was quickly followed up by the Galaxy S4 Mini, Galaxy S4 Active, Galaxy S4 Zoom, and Galaxy S4 LTE Advanced. Samsung used the same tactic when it came to this year's flagship Galaxy S5.

The Samsung Galaxy S5 family consists of the Galaxy S5, Galaxy S5 Active (AT&T), Galaxy S5 Sport (Sprint), Galaxy S5 Mini, and Galaxy S5 LTE-A.

HTC has been taking a page out of Samsung's playbook and launched the HTC One Mini and HTC One Max as variants of its 2013 flagship HTC One. The company has already added a One M8 variant with the HTC One Mini 2 and now it's about to add a new variant of the 5-inch HTC One M8.

We recently reported that HTC was rumored to be getting ready to unveil the HTC One M8 Eye on Oct. 8 and it now appears that the HTC One M8 Eye will launch at the event, as an official press image of the smartphone has appeared on Weibo.

As you can see in the image above, the HTC One M8 Eye retains the HTC One M8's unibody aluminum design, screen size, and specs, but trades in HTC's 4-megapixel UltraPixel rear camera for a more powerful 13-megapixel shooter. The HTC One M8's secondary rear camera is still on board and is used for depth of field measuring.

The HTC One M8 Eye is expected to feature a 5-inch 1920 x 1080 Full HD display, run Android 4.4.4 KitKat, and HTC Sense 6. It will be powered by a quad-core Qualcomm Snapdragon 801 processor and 2 GB of RAM to keep things running smoothly.
