It's actually happening thanks to Bandai Namco.

Pokemon Snap is going digital.
"New Pokemon Snap" was announced today for Switch in the Pokemon Presents presentation. More Pokemon than were present in the 1999 N64 game were shown in a 3D environment.
No release date was given for the project. According to the copyright notice at the end of the presentation, New Pokemon Snap is developed by Bandai Namco.
It's cool to finally a new Pokemon Snap that I see Nintendo is irritating us with the "New" naming convention again. That sort of naming make gaming seem very disposable, which is odd coming from Nintendo since they seem very aware that their games can be resold on later platforms for all eternity.
The trailer looks nice but it looks like you're still on rails. That's fine I guess but I always imagined a Pokemon Snap where you can freely wander through an environment and try to get photos of Pokemon, like how a nature documentary filmmaker would do it. I figured the on rails element was more due to the limitations of the N64 hardware and that a lot more could be done with the photography concept. This looks a lot like it just makes things prettier and has more Pokemon. Of course by now I figure fans are just happy to have another Snap game.
