Does anyone know if it matters that I'm not in my "home" region to get the update? I'm traveling, so does this mean I get it based on my location, or my account? I'm guessing it's my account, but I'm curious.
You get it based on your phone. The IMEI number, it's serial number so to speak. When your number is up you will get it, won't matter where you are as long as you are on VZ's network. When your number is up is totally unpredictable. Two phones with numbers right next to each other could get it days apart.
