And if the implication is that they'll port those iOS games to Mac, then I wouldn't count on it if it takes even a single iota of extra effort on their end. There are more Linux gamers than Mac gamers, and yet game devs still can't be arsed to test their games on Steam Deck.
Tale as old as time.
Apple has historically been terrible about committing to gaming which has led to game developers ignoring the platform. I do hope that Apple actually stays the course this time around and with the M* series of chips they've raised the floor for what game developers can count on having available.
I really thought they would have made a bigger play for gaming on the Apple TV (The hardware, not the app, not the service, I still can't get over that...), they pushed a little at the start but with most Apple gaming initiatives (aside from mobile) it seems to have fizzled out.
The games will come to all Apple Silicon devices as the architectures are very similar if not the same (M1 iPad vs M1 Mac). Apple also released the Game Porting Toolkit and I can already play games at decent framerates with Whisky [0] which utilizes GPTK. Keep in mind this is basically beta software that's not even for the end user to use but as a developer tool to help port their games over.
And obviously the games when on iOS won't be played with touch controls, it's for playing with a Bluetooth controller.
