HTC Launching M7 with Ultrapixel Camera?? Where did Megapixel Go??

We have seen countless leaks of HTC M7 including some image and some spec related. And on the more entertaining side, we have even seen HTC CEO Peter Chou lead a crowd in a chant of HTC M7. Anyway, included in those spec related rumors was the mention of the handset having a 13 megapixel rear-facing camera.

It seems though, that may not exactly be the case. According to Pocket-lint, HTC is going to be switching from Megapixels to Ultrapixels. This move looks like it will begin with the launch of the M7 smartphone. Touching on the 13 megapixel rear-facing camera, it is now being said that the HTC M7 will launch with 3 - 4.3MP Sensors, which when combined will add up to around 13MP.
