Here are my Ruby and Sapphire DS/3DS predictions:
- They will implement seasons into it.
- The walking Pokémon feature will be brought back
- There will be new puzzles and such to find Legendary Pokémon ie Regirock etc.
- Improved graphics
AND MORE TO COME SOON...
Ruby and Sapphire remakes have long been speculated for since the release of Pokémon HeartGold and SoulSilver because these were the poorest quality games, and I support this idea, I know RS3/DS will be a reality soon!
