At this point, we have only got a low quality render but it does show the front and back sides and along with that dual cameras on both the back and the front.
Information previously leaked suggests that the device will come with the Snapdragon 845 (par for the course this year), along with a 6 inch screen. 6GB of RAM, Oreo on board as expected and a larger battery than previous years. Other information suggests that this will be HTC's only flagship of the year, but that has been said before and still refreshed versions have been released.
HTC have obviously been struggling of late, but their Pixel 2 design was highly successful which led to the team behind that moving over to Google directly, so it remains to be seen what the long term impacts of that will be and if this is the start of something new, or another final nail in the coffin.
