If they can get remote play to be convincing. Or just people that are brand loyal/don't know any different about a handheld. Sold out is one thing but low production runs/what stores receive is another thing besides through Sony directly. It's niche.
If Sony gave people Dualsense grips for tablets besides the backbone I think it would have been fine.
Sony does niche well with still MP3 players that are more Android smartphone like, smartphones with particular camera tech, among other things if were just gaming only overlook compared to their other tech focused parts of their business.
Then again the Sony Q dual screen phones were too early as well (PS Home on PS3 alongside Second Life and others on PC and well Second Life lives on).
Pocket PCs they, Samsung and more made disappeared because of the iPhone/not being suitable form factors. But Steam Deck comes out then the business focus of Pocket PCs/PDAs of the past (GPD and other small companies making pocket PCs still for years as handheld PCs with buttons for games after in a niche space).
They kept the Vita alive for 10+ years production they didn't kill it off like Sega did the Dreamcast. Remember the remote play/second screen apps were still Vita exclusive up until the Android support in 2019. It was only unofficial apps prior. That's like keeping Stadia around for Pixel phones only levels of keeping something exclusive for years than to other Android phones (if Stadia still existed that is to make a scenario comparison regardless of the reality).
So while Dreamcast games went until 2007, Vita still did and Vita production still did in those 10 years. They could have but they didn't did they. Sure no first party support but that's just downscaling, it's not fully ignoring it is it as much as people like to say something is dead because they don't like it.
If people want the PS5 and anything orbiting it like Sony does by all means even though other options exist of PS4, phones/tablets and PC. If Sony gave people Dualsense grips for tablets besides the backbone I think it would have been fine. (repeat on purpose started here moved it up).
If cloud comes later not surprised they are still working on their cloud services with Azure I assume besides PS Now level ones of PS+ still they have had for many years now.
A niche product isn't a bad thing but no dual screens? What was the point in inside and outside asymmetrical multiplayer with the PSVR, split screen with TV/PSVR, Playlink (PS4 smartphone connected party games), or Vita support for dual screen in Playroom or if Deux Ex used it like Wii U did.
Remote play has always been there since PSP but how they market it/how the future is who knows (even crossave with PS2/PSP thanks Sega with Outrun 2006, and likely other companies maybe did too I don't know but still worth noting).
Lacking dual screen or android is enough for me to say I don't care about it. Android I can let go of but dual screen seriously. I mean let Indies do something with the device at least come on. Not a casting screen that's useless. I don't care if wifi and good connection is involved wifi 5 or 6 and whatever distance you can get with your PS5 on to play on the go and if Vita could do it as well 10 years prior (let alone Wii U with a power bank/second screen for some games and your good to go locally on the road no need for internet at all for singleplayer games) and better probably. XD
They need more convincing aspects to it.
I can take no game support for it/an eshop but no dual screen, split-screen marketing or anything exciting just casting. I can cast my phone to the tv and have more fun. I can cast my phone playing PS5 games back to the TV if I wanted to be stupid just to prove a point.
