The back of the device is in keeping with the stylish One (M7), One M8 and One M9. The front is a different story, however, due to the absence of HTC's trademark dual speaker grills. Instead, there's a physical button near the bottom, which possibly serves as a home shortcut and a fingerprint scanner. It's reminiscent of the One A9, a successor to the One M9 which our own Chris Velazco criticized for sporting a "new but derivative look."

Under the hood, the phone is rumored to run a Snapdragon 820 processor, 4GB of RAM and 32GB of internal storage. It's all speculation for now -- while most of the surprises appear to have been leaked, there's only one way to know if they're accurate. HTC will be making its announcement at 8am ET/1pm BST tomorrow, so check back here for the full rundown.
