Did a little more homework.
4.1 JB was announced back around June. Verizon nexus got it rolling out as an official OTA on Sept 21. I'm not sure when the GSM phones got it... but lets just say it was a little over 2 months.
Now, I forgot the Verizon Gnex finally got added back into AOSP, so you guys should see a much faster update than last time.
Im pulling for ya!
