Hakuna matata...the Verizon circle of life.
If things run true to form, either Verizon will say (or rumor will have it that Verizon promised) to provide Jelly Bean in the first quarter of 2013. Around January 1, people will start posting messages like, "My phone keeps timing out when I try to check the update status. Does this mean Jelly Bean is about to come through?" Someone in Colorado will SWEAR that they got it OTA overnight, but screenshots will show they're still on the original stock ROM.
In February, someone over at XDA will announce a leaked version and release a custom ROM with it. Everyone will love it and complain that Verizon isn't releasing it because they haven't been able to get all the bloatware to work correctly.
In March, threads will start that say, "Verizon promised this in Q1 and all the other carriers released it back in October! I'm leaving them forever if they don't release it by XXX." This will continue until March 28, when threads will start, "Verizon has 48 hours until it has broken another promise."
On April 1, a lot of jokes will appear about Verizon and Jelly Bean being a joke, then despair will set in that Verizon will never release Jelly Bean for the phone.
In the beginning of May, Jelly Bean will appear OTA. Half of the forum members will complain that it bricked their phones/trashed their SD cards/changed their plans/ruined their battery life and the other half will say they're not downloading it because they've been using a custom ROM newer than Jelly Bean since last October.
