The resin mock-up shows the BoomSound speakers on the front of the phone, and on the back there apparently is an opening for a double flash. The rear camera is tipped to remain a 4 UltraPixel snapper while the front-facing camera will weigh in at 2.1MP. 16GB of native storage will be on board with a microSD slot available. We could see a 32GB variant of the phone, as well. Android 4.4 will be pre-installed out of the box.
One published report on Wednesday suggests that we will see the HTC One 2 (or whatever it will be named) introduced at MWC 2014 in Barcelona next February.
