The Game Boy Advance had a remake of RBY, the DS had a remake of GSC, and the 3DS had a remake of RSE. With that in mind, it's entirely possible that one of the upcoming Pokémon titles for Switch will be a Sinnoh remake.

With that in mind, what would you want in a remake of these games?
> Better Pokemon distribution so Fire types aren't limited to Infernape and Rapidash
> Difficulty settings a la Black 2 and White 2, to accomodate everyone from Let's Go players to seasoned veterans
> Choose between either adding new evolutions like the Sinnoh games, Mega evolutions like the Kalos games, or alternate forms like the Alola games and then stick to one
>Include online multiplayer for the underground
