Remember the Twitter folk that leaked a name change for the HTC M7 to the HTC One yesterday? They know more than you or I might think. In fact, they seem to be dripfeeding details to us on a daily basis.Hot on the heels of the name change comes what is said to be a press shot of the upcoming flagship phone from HTC, again produced by the @evleaks Twitter account.The leak gives nothing more away than the photo and the caption 'HTC One, 2013' on the face of it. But with the track record for leaks via that account, we're sensing it is, at least, genuine.Does the photo tell us more? Well, a little. For a start, it shows us what HTC thinks we want to buy in 2013. But specifically, it also shows a contrasting top and bottom with speaker grills, a row of capacitive buttons and what could be a first glimpse of HTC's latest Sense interface, Sense 5.Outside of the photo, we have previously heard the phone will pack a 4.7-inch 'SoLux' screen, a 1.7GHz Qualcomm quad-core processor, 2GB RAM, 32GB of storage, Android Jelly Bean and a 13-megapixel camera.All should be revealed on 19 February at a press event. If there's anything left to reveal by then.
