This may be disappointing news for owners of the Google Play Edition of the HTC One M8. A couple days ago, we reported that the GPE HTC One M8 (and M7) would probably be getting a rollout of Android 5.0 Lollipop on Friday (today). This was reported in a Tweet from HTC themselves.
Sadly, it has been delayed due to a need for "New SW" (new software). This news was also reported by HTC in a Tweet. As you can see from the screen-capped image of the Tweet above, there's no timeline given now, so it could take days or weeks. We will keep you apprised when we find out more.
