HTC One's successor codenamed M8 and also known as One 2 and Two should launch this March, following an MWC debut in late February. As the rumor has it HTC M8 will be powered by the latest Qualcomm chipset (currently the Snapdragon 805) and will come with a bigger, at least 5", screen of QHD resolution (1440x2560px) display.
HTC will keep using the UltraPixel technology for its new flagship, though the new camera will feature twin UltraPixel sensors. This should improve the auto-focus, image quality, and depth of field. There is no word on the resolution of the two UltraPixel sensors though, nor more details on their exact manner of operation.
HTC will probably announce the One successor at the MWC in Barcelona by the end of February.
