In the press call in response to a question about the new cameras potentially being effected by rain and snow, Elon said that the 3 forward cameras high up at the center of the windshield have their own heater element to prevent ice buildup and that they are in the area covered by the wipers, the two side cameras are high up on the B pillars, and the the two rear quarter cameras are in the "repeater" side area of the taillight housings in an area where snow and ice buildup does not typicall occur. The rear camera is in the same place and he said nothing about any new feature to keep that camera clear of moisture. That is the only area I would be concerned about because when it rains the rear camera is often useless.
Elon also said that the car would alert the driver if any of the camera images were not usable by the software so the driver could clean the camera, a very useful feature.
