I can confirm that they are beginning to push the official OTA. I received a replacement MoPho yesterday in the mail and still have the old MoPho since I haven't received the Return Kit to ship it back to Sprint.
I was erasing all the info on the old MoPho, I decided to connect to my WiFi connection and see if there were any updates, I pressed update the Motorola Software and BEHOLD it said there was an update available! It is now updated to:
System Version 45.2.5MB855.Sprint.en.US
Baseband Version n_01.28.05s.fk
Now my NEW MoPho, still hasn't received the update.... let's see what happens!
