Thinking a little more about this...the only way I see Sony realistically making another portable in the future is as a streaming device once 5G has a decent presence (or even LEO satnet, depending on its success and required antenna size). Your device would link up with an expanded PS Now or your PS5 via remote play. There would be a data subscription, of course, but maybe they could roll that into a Plus or Now sub, somehow. With most of the processing being done remotely, the device wouldn't need powerful, expensive hardware and could be priced relatively cheaply, say in the $100-200 range (or even subsidized with the right subscription). Of course, this technology wouldn't require its own dedicated portable, either. Any 5G smartphone or tablet could access the same services with a PS app and linked DS5.
