exactly.Nintendo (love em or hate em) beats to its own thing and why they've been untouchable in handheld even if spec wise theres better options.
They found out most people dont care about newest hardware if the content is great.
won't happen as would make their PS Portal future versions worthless.
The main issue Sony doesn't get, is that even the Steam Deck and all its clones by Lenovo, ASUS etc are all niche products, including the Steam Deck. Sony loves to bail on its own PlayStation products when the numbers look bad. The PS Vita which I own was a lovely piece of kit, especially the OLED screen. Sony blew all that away by pricing it the same as the PS3 Slim, $299 and the memory cards were ridiculously priced as well.
Their PS Portal is basically a regurgitated PS Vita because that's what Sony turned that into, a streaming device that allowed you to stream PS4 games via the internet.
Nintendo is a rare breed as you've indicated. They do things their way much like Apple when Steve Jobs was in charge. But with Nintendo they have incredible game designers that somehow always seem to pull a rabbit out of their hats because even their franchise IP's always offers a new twist to attract the attention of gamers.
Which is why I'm not sold that their will be a Nintendo Switch 2. It could be something totally different where Nintendo cooks up something entirely new. We should find out next year what their next system will look like.
