If you own the HTC One M9 and are on Verizon, then you won't have to wait much longer for Android 6.0/Marshmallow. The update will be rolling out February 16th (which happens to be tomorrow). This follows hot on the heels of Sprint's rollout of Marshmallow to their HTC One M9 (last week). It turns out it will likely coincide with T-Mobile's rollout as well, which is expected to come tomorrow also.
What a shock! Big Red is usually the last to see big updates rollout for flagships, but this time it will be AT&T who gets Marshmallow last for the HTC One M9. Do you think this is a new trend for Verizon? Probably not...
