Tesla has also just entered into an agreement with Samsung to produce multi-megapixel cameras instead of the current 1 megapixel units. This change will likely happen within a year or so Tesla time. The radar will require a complete rewrite of the FSD software, and a change to start installing it in producing newer cars. This will likely take longer, and it will likely eventually become a separate software release over time that legacy cars made now will not get. They will complete the basic FSD coding going on now to provide a FSD system limited by current hardware. I doubt Tesla will be retrofitting new processors, cameras, and radars in any current cars.
