There are billions of cameras, and phones with cameras, in the world. They come in many sizes, from tiny to huge.
Over 14 trillion photos are taken every year.
Seriously, no one needs to make any new cameras of any size for a looooong time. At least they don't need to make any more cameras for photographers. For the gear hound addicts and the people who just want to own the latest electronic marvel, these are people who probably want, but don't need, new cameras.
