People felt the same about the retrofit for the swiveling display, and that never happened, either. Never, ever assume Tesla will retrofit this, as the number of things they do retrofit is very, very few. They don't offer an official retrofit for the rear screen upgrade, the swiveling display upgrade, the updated headlights or tail lights, the Steam support etc. The only part they MIGHT retrofit is the new steering wheel/yoke when that's available en masse, because of the warranty issues with the crap existing material.
Of course, I hope to be wrong about the front camera, but I'd say the chances of that being ever offered as a retrofit is slim to none.
