That is simply not going to happen. Google tried working with Verizon with the Galaxy Nexus, but delays in updates infuriated users (and probably Google as well)...until Verizon allows *Google* to control the updates, I seriously doubt Verizon gets any more Nexus devices. Verizon was probably forced to make this concession for Apple since the iPhone is such a huge seller, but as long as the Galaxy S line and other non-nexus Android phones continue to sell, they don't really have incentive to cave into Google the same way.
Not necessarily stating fact, just my opinion.
