Does material nonpublic information cover knowledge of unannounced products?
There's the question whether knowledge about unannounced products is actually "material" if everyone (the public) knows that something new will be released. If you work at Apple on the development of the iPhone 8, that's not material. If you worked at Apple and you knew that they stopped developing new phones, that would be very, very, very material information.  The important thing as far as the stock market is concerned is what sales look like, and that's not something you know as a product developer.
