Totally makes sense if they could do it. I have zero understanding of the economics but I think it makes sense and the past reasons of why Vita failed don’t exist today.Most people have a poor understanding of game industry economics. I think this is a no brainer. Only thing stopping Sony would be TSMC 5/7nm wafer availability. They need to prioritise chips for the PS5 before considering new platforms. If the chips situation is resolved, I can see Sony launching this. It's basically another premium accessory/device they can sell to enthusiasts.
Battery would suck and it would probably be expensive but Id buy day 1
