It's not like HTC isn't aware that missed the self-imposed deadline. In responding to a tweet wondering about the missing update, the Taiwan based OEM said that it is aware that it missed the deadline, is working with Verizon to complete it and will notify customers when it is ready. Did HTC give us a coded message by including Verizon in its response? The carrier is known for being particularly compulsive with its update testing and HTC might have been telling us that Big Red is responsible for the missing update.
