Good luck in getting a answer.
We have all been asking the same question for over a week now and keep getting conflicting information.
I do not know of anyone that has received Marshmallow. The Manual System Update (OTA) and the Verizon Software Upgrade Assistance tool (PC-USB) both do not work so it looks like it has not been released yet.
If it has been delayed, Verizon needs to tell us and update their web pages with the correct Marshmallow release date.
I am right now downloading the first update for getting ready for marshmallow. I will let you know when I finish downloading first update and then hopefully 2nd update will go with no problems and then I will have marshmallow.
It has begun! My Turbo2 (which I just had checked earlier in the morning with no luck), just started downloading and installing the update!
