I was thinking surely there is a market for this. Xperia Play came out 10 years ago. Since then handheld gaming has advanced so much. People are playing Fortnite and Minecraft on phones with full gaming controls. We have XCloud and other streaming services for playing games. Emulation has improved so much on Android we got 3DS and Wii emulation now and Retroarch is so much better now. Yes people can just buy attachments or control games with any Bluetooth controller. But honestly I don't think I would be bothered to carry another device when I'm out but I'd easily play more games on a phone if it had slide out controls.
Phones have also reached a level any mid range phone has good enough specs so I'd easily sacrifice some features from the bug guns like Samsung Galaxy as majority of mid range smartphoned just reached a level it's enough power.
