HTC countdown timer clicks down toward HTC One introduction on February 19th15
To make things interesting, every time the countdown timer reaches 51, 41, 31, 21, 11, or 1 second, the '1' becomes highlighted in a green color and the background shows off an image from the phone itself. Get it, HTC One=1. We are as sharp as a tack today, folks! So it looks like those who were hoping that the HTC M7 name would somehow be used for the device might as well hang it up now. You know who you are.
