I also think there is zero chance of Astro coming to Nintendo Platforms, that counters the whole branding of it being PlayStations flagship platformer designed around PS5 hardware. If anything lands on Nintendo it will be low value spinoffs (ala Lego Horizon) intending to bring people back to playstation or old PS4 era games. Astro is doing the exact job Sony intended it to do and is charting longer than games like Forbidden West, Ratchet Rift Apart etc so I don't think there is much grounding in any port talk for the time being.
"37% of the game's buyers are new users who haven't purchased a first-party title from PlayStation in two years."
