Game consoles are also not hugely profitable. In fact they are sold at a loss for the most part for the first few years. Microsoft loss billions selling game consoles on the first two or three generations. Even now, the mobile app market is larger and more profitable than the console market for Apple with them taking a 30% cut.

On top of that, Apple already announced the subscription Apple Arcade service and their games will run on iPhones, iPads, AppleTVs and Macs.

Between Microsoft and Sony, they sold a little over 100 million of the current generation consoles during their entire existence (https://www.cinemablend.com/games/2417541/ea-reveals-how-man...) - many of them at a loss. Apple sells 50-70 million iOS devices every quarter.

Heck Apple will probably sell more Watches (at a profit) than that during its first 5 years.

People are already spending more time on mobile devices than consoles.

As far as cameras, the standalone camera market has been declining for years because of the smart phone. There is only so much you can do with cameras in phones because of both physics and the cost has to be low enough to make the entire phone affordable. I’m sure no one at Apple is thinking about releasing the Apple QuickTake 2.
