This month’s Xbox Live Rewards survey may have leaked HTC’s (2498) upcoming flagship Windows Phone 8 device, the HTC Titan III. Every month Xbox conducts a survey where participants can earn points that can be redeemed for variety of services and products. The latest survey asked users to gauge their level of excitement for the iPhone 5, DROID RAZR Maxx HD, Nokia (NOK) Lumia 920, Samsung (005930) Galaxy S III and the HTC Titan III, a device that has not yet been announced. The Titan, also known as the Zenith, has been rumored to be HTC’s third and perhaps most exciting Windows Phone handset. The smartphone is believed to come with a 4.7-inch Super LCD 2 display, and feature a quad-core Snapdragon S4 Pro processor and an 8-megapixel rear camera. The Titan III was previously rumored to launch in the fourth quarter of 2012, however it will likely miss that time frame.
