Headphoneus Supremus
It's clearly part of the U series, so although I cannot confirm this (the only "leaks" that seemed to confirm it have been dismissed as fakes) it is hard to believe that it will have a completely different design language from the U Ultra and U Play, both of which are glass designs.
Hard to say one way or the other.
It might also be HTC Ocean which suggests it might not have anything to do with the HTC U Ultra (I hope it doesn't).
if it turns out to be jackless just like the HTC U and the HTC Bolt then its a no-go.
