We've seen Android 4.2.2 for the Verizon Galaxy Nexus surface a few weeks ago. Now they are actually pushing it out starting today, March 19th. No this isn't a rumor, it is confirmed. It looks to be the same build that leaked out not to long ago which was Android 4.2.2 build JDQ39. So far the famous support documents have not appeared on the site yet, but they should be showing up anytime now. It's safe to assume that it'll be build JDQ39 since that is the latest build of Android. You can also grab the update manually and update your device yourself.
Here's how you can install it (thanks to Droid Life for the instructions):
*In order to apply this update in any of the situations below, you need to be 100% stock Android 4.1.1 (JRO03O). This is not a ROM that can be flashed over another ROM. It's an update.
*For 100% stock Android 4.1.1 (JRO03O), but with root and custom recovery.
*Keep in mind that this is technically a test build.
1. If you are rooted and with a custom recovery, download the file from above to your phone.
2. Reboot your phone into recovery.
*Hold both Volume Up and Down plus Power at the same time until you see a "Start" button appear.
3. Choose "install zip from sdcard."
4. Find the file you downloaded, and select it.
5. Once it finishes, reboot your phone and enjoy 4.2.2.
Instructions (non-rooted "adb sideload"):
*For some reason on my Galaxy Nexus, I did not have the "adb sideload" option to update via stock recovery. If you do, these instructions are for you. If you get into stock recovery and don't see the option, you'll need to jump down to the next set of instructions.
*I'm also going to assume you know adb commands if you know about the sideload command.
*These are also the abbreviated adb sideload instructions. For the full guide, check out this post.
1. Download the file from above to your computer.
2. Plug your phone into your computer and type "adb reboot bootloader" in your command prompt.
3. Your phone will boot to fastboot.
4. From here, scroll down with Volume Down to "Recovery" and select it with Power.
5. When the exclamation point and Android appear, tap Volume Up and Power at the same time.
6. You should now be in recovery.
7. If you see "adb sideload" as an option, choose it. (If you don't, jump to the next set of instructions.)
8. From your computer terminal, type in "adb sideload <filename of the update file>"
9. Your phone will prompt you with a set of instructions for updating.
10. Follow them, update your phone, and enjoy.
*If you tried the instructions above and are not seeing "adb sideload" as an option in stock recovery, you'll have to use these instructions. The only way to update at this time, is to temporarily flash a custom recovery. It's not hard and will not ruin your phone by any means. Temporarily flashing means that after you install the update and reboot, your stock recovery will return. This will not root your phone.
*This Nexus toolkit is the one I've chosen for this set of instructions. [XDA thread]
*Once downloaded, run the .exe file (Windows) and follow the install instructions. Once installed, hit up the instructions below.
1. Download the update file from above to your phone's storage.
2. Using the toolkit above, choose LTE Galaxy Nexus with build 4.1.1 (JRO03O).
3. From the main menu, choose option 10, "Boot to custom recovery without permanently flashing it."
4. Then choose option 1, boot to Clockworkmod Touch Recovery.
5. Follow the next on-screen instructions to boot into Fastboot mode.
6. Watch your phone boot into fastboot, flash recovery, and then take you to recovery.
7. From there, choose "install zip from sdcard."
8. Find the update file you downloaded in step 1.
9. Select it and install the update.
10. Once finished, reboot, enjoy Android 4.2.2 and your stock recovery.
So now your Verizon Galaxy Nexus will be up to date, at least until Google I/O comes around with Key Lime Pie. Nonetheless you'll be getting lock screen widgets, photosphere and all the other Android 4.2.2 features on your Galaxy Nexus
