Verizon has approved an update to 4.4 and announced that the Droids would receive the update starting Dec 19. The last official update that I saw from Verizon and Motorola is that the update is continuing to roll out, slowly. What *seems* to have happened is that several people had an issue with the update, so the update was stopped, and there are rumors that there is a new test about to begin.
So, a Maxx without 4.4 is just waiting for the update to resume at this point.
FWIW, I have 4.4 on my phone. It's running fine.
