The HTC 10 is getting unveiled tomorrow, but why wait? You can watch a leaked promo video right now. The video doesn't show what we didn't already know (the design of the 10 has leaked many times before), still it gets up close and personal with the aluminum unibody of the upcoming flagship.
Recent teasers promise great battery life, amazing camera (perhaps including an OIS-enabled selfie camera) and more. The announcement will be tomorrow, but it's going to get very late if you live east of the Atlantic so you may have to wait until Wednesday for the official deets.
