The Android 3.2 update for the Motorola XOOM 3G on Verizon is rolling out now to soak test members. If you are a part of that super secretive group, then be sure to head into Settings>About tablet>System updates to pull it.
Hopefully this is a sign that the rest of us will see it either tonight or some time tomorrow.
Update: If you would like to manually download the file, grab it from Google here. Hoping to have manual update instructions soon.
