Looks like Verizon has started rolling out the Marshmallow update to BlackBerry Priv units on its network. According to the information available, at-least one Verizon Priv unit has received the update. Priv's software update page on Verizon's website doesn't say anything about the Marshmallow update. So, there's currently no confirmation on whether it's a public roll-out or just a soak test, but even if it's the latter, Verizon Priv users will be happy to know that the update is imminent.
