Most likely speculation, imho, is that the b-pillar cameras are moved to somewhere on the front fenders, as there are now four cameras labeled 'FF' (front fender?). With the main forward cameras reduced from three to two, that leaves three new cameras. There are three cameras labelled 'SVC', 'F', 'R' and 'L' (front, right and left). Green's speculation was that these are bumper cams as Tesla's parts catalogue says SVC in the bumper cover description, but there's alternative speculation that the SVC refers to 'surround-view camera', a terminology used by Mobileye and others for the 360 degree birds-eye parking camera system. That's typically four cameras, so why only three added here - I guess because the existing backup camera meets the needs for the rear SVC. If this is true, and seems more likely to me, it'd be one in the front bumper, but the side ones more likely in the mirrors like many other vehicles with a 360 birds eye view, or even using the existing b-pillar location. Might all give USS-less parking a fighting chance!
