The possibility of these remakes comes from the precedent set by the releases of remakes for the past two Generations. Pokémon FireRed and LeafGreen, the Generation III remakes of the original Pokémon Red and Green, and Pokémon HeartGold and SoulSilver, the Generation IV remakes of Gold and Silver.
Based upon the previous remakes being nearly exactly the same as their originals far as storyline goes, the assumed storyline of the remakes would thus follow Ruby and Sapphire very closely, with the player starting in Littleroot Town and traveling across Hoenn.
Shortly after the announcement of Pokémon HeartGold and SoulSilver Versions in 2009, some fans began to expect a third pair of remakes, this time of the Generation III games. However, this time the majority of fans expect it during Generation V.
Those who expect remakes also point to allusions to Ruby and Sapphire in Generation IV's five games.
In Hearthome City there is a character that states that he traveled all the way from Hoenn to compete in the Pokemon Contests of Sinnoh.
In Diamond and Pearl a single Lava Cookie is given to the player as a reward for finding the Suite Key of a lady at Valor Lakefront. In Platinum she gives the player a White Flute, and states how it is only found in the Hoenn region.
In HeartGold and SoulSilver, when the player meets Bill he mentions the Hoenn region, and that he worked with Lanette there.
The Weather Trio of Hoenn appears in the games at a location called the Hidden Tower this tower was built by people of Hoenn, and during the in-games events revolving around their capture the legend of Hoenn's creation is recounted.
- Since before the release of HeartGold and SoulSilver, the prices of Generation III games have increased dramatically in online auctions. This demonstrates an increasing demand for the games, and incentive for Game Freak to make updated versions in the future.
Critics of the remake speculation have held that the availability of 3rd Gen Pokémon, including many of the legendary Pokémon, in the Generation IV games means that there is no need for remakes. Others criticize that if Ruby and Sapphire are remade Pokémon Diamond and Pearl would be expected to be remade.
Many names are theorized by fans the majority are in the format "XRuby" and "YSapphire", following the pattern of previous remakes.
