If you own the Moto X on Verizon and are not a part of the most recent software soak test, you may be able to pull the update anyway. A number of readers within the last few minutes let us know that they are receiving the update, yet are not a part of the soak group.
We have the full changelog at this post.
To check, head into Settings>About phone>System updates.
Cheers Brent, Dustin, Roth, @AaronWltrs and @arrow2theknee!
