I can't see Google allowing Verizon to lock it down hardcore like Motorola. Google knows if they did the Nexus brand will be tarnished as it wouldn't be a pure Google phone with a tightly locked bootloader. Google understands that users don't want to be told they can't do what they want to do with the phone they just paid for. That's like a car dealership saying you can't install an aftermarket system into the car you just paid for. I'm going to go and say if it's locked down there will be a way to unlock it easily. You just have to have faith in Google because I don't think we would be seeing a Nexus device on Verizon unless Verizon agreed to let Google do what they do best.
