Here's an indirect follow-up article regarding the Verizon HTC One M8. In regards to the Android version of the Verizon HTC One M8, a new report indicates that Android 4.4.3 will be delayed until mid-September. HTC's US president Jason Mackenzie just confirmed this on Twitter recently.
We aren't sure why Big Red is so slow with this update. The T-Mobile version already started receiving Android 4.4.3 today. Of course, this should come as no surprise since Verizon's vetting process tends to be longer than any other carrier. Apparently, Mackenzie indicated they had problems with the GPS that needed to be tweaked and re-certified by Verizon.
We will keep you updated when a more specific date is revealed.
