It looks like the cat is completely out of the bag now. The HTC One M9 has now appeared in what appear to be promo videos directly from HTC. They introduce users to the device, show off the camera, and HTC Sense 7.
With these new features revealed, it seems all that is remaining to be told is a specific release date for the device. With HTC’s press conference occurring on March 1st, it won’t be long until that is told.
