If a Verizon version of the Passport existed, I would be out of the NDA by now anyway. The NDA only lasts till the announcement is made and it would have been announced already if it was going to happen anytime soon.
The NDA would prevent me from saying that it is coming if they do start talking about it soon, but nothing is preventing me from saying that there has yet to be a single word said to me about the BlackBerry Passport on Verizon Wireless, which leads me to believe that it won't be happening. If it does happen, it won't be any time soon. Testing takes a while to complete after all.
