Sony have experimented so much with handhelds, and have never really seen mass market success. I suppose it could be argued that they never quite nailed the hybrid concept (as docking your PS Vita and using it with a TV certainly isn't the seamless experience you get on the Switch - this is also true for Remote Play).
But I really wonder if Sony is re-thinking their approach behind the scenes, and whether they will ever offer a portable or handheld experience in the future.
It seems to me that there is still a large market for home consoles and gaming PCs. Even with the rise of handhelds, it seems unlikely that this "dedicated device" market will entirely disappear. I wonder if we should be seeing this as a zero-sum game, or rather, an overall expansion of the market.
I'm not sure what the current stats are, but I'm sure I've read that more and more folks/households are purchasing multiple game devices. So the idea of owning, say, a PS5 and a Switch, is probably going to become more and more common. Whereas 10 or 15 years ago - and certainly earlier - it was probably true that households tended to buy into one single platform.
