Will the Droid Turbo get Android M?

I have a Galaxy Note 2 right now, and my contract ends on the 31st of August. I would like to get a new phone then, and the Droid Turbo is looking like it will be my choice. The only thing I am worried about is, will Verizon update this to Marshmallow? I don't want to get a new phone and be stuck on an old OS. Also, is there any info on when Verizon will be releasing a new Droid? I would be willing to wait a few months if they are coming out with a Turbo 2.
