The HTC M8's alleged dual camera system demoed at MWC, computational photography magic and optical zoom in tow?

UPDATE: We met Core Photonics and they confirmed that this is not going in the M8! 

The new system will make use of two photo sensors - possibly 2MP and 4MP, and a pair of lenses that features a standard wide angle lens and a tele lens for long focus. Computational photography algorithms will use combined imaging data from the two sensors to create superior photos and give additional photographic options.

All of this has definitely piqued our interest in HTC's upcoming 2014 flagship. But will three cameras and extended photography options be enough to make the millions of Galaxy S5 buyers regret their purchase? Or there are more tricks up the Taiwanese's sleeves? We will learn on March 25 at HTC's official event.
