Here is an update on this. I spoke with my contacts in Nissan product planning and confirmed that the RVC is NOT standard on any of the 2013 LEAF models. Quite probably what happened is that the OP of this rumor saw a RVC that was part of the AVM on a 2013 car and did not notice the other 3 cameras.
With that said, look for a return of the RVC on the 2014 LEAF when the NVSS section mandating RVCs kicks in next year. Nissan is assuming that the NVSS standard on RVCs will be published shortly.
I will also pass on the note about customer care incorrectly listing the RVC as standard (though the transcript below, does not actually say that the RVC is standard, only that the AVC is optional. It looks more like a typo than an affirmation).
This:
Mike: I have heard that the Rear View Camera Monitor has been determined to be Standard on the 2013 SV/SL -- can you verify this? And the All Around Camera Monitor is optional on SV/SL.
Amanda: Yes, correct on our SL and SV models. The all around is an option that [can] be added to the vehicle.
Probably should have been this:
