Wait no more, grab your device and go to Settings>>About Phone>>System Upates and see if you can pull the update. If you are not able to, wait a little while before you try again. You might also receive a notification pushed to you.
From the looks of things, Motorola (Google) has removed almost all the Motorola related bloatware allowing users to enjoy Android in a near-stock environment. Motorola had been paring back the old “Moto” themed user experience for a while now, so this move is not too unexpected. If you are running Android 4.0 ICS, expect the download file to be about 338MB.
The Android 4.1.2 Jelly Bean rollout began in phases a couple days ago, but not everyone has been getting the notification. RAZR and RAZR MAXX owners should be able to query and “pull” the update manually.
