That is a pretty big jump to get to your conclusion... or are you basing that on the November release of ICS and Q1 2012 release of the Nexus to be fact?
You know I like to ruffle feathers and my speculation is just as good as any unnamed source. Given the release history of Android, if this supposed "source" says Verizon's version won't be hitting until Q1, I think those are the two most probable scenarios if this "source" isn't full of it.
I AM the guy that speculated that the reason VZW didn't get the GSII isn't because of this phone but because Samsung couldn't get their chipset to work with VZW's LTE radios without adverse effects to perfomance and/or battery life.
