With the launch of the $399 Hero 5 Black and the $299 Hero 5 Session, GoPro is retiring some of its older cameras, and renaming one. The Hero 4 Silver ($399) and Hero 4 Black ($499) are being discontinued, while the Hero 4 Session is being renamed the Hero Session, and its price is dropping to $199.
