Numerous hints seem to indicate The Pokémon Company is gearing up to remake Pokémon Black and White. Remakes are a proud tradition of the Pokémon franchise that dates back over 20 years to the release of Pokémon FireRed and LeafGreen. Because many older Pokémon games were released on consoles no longer in service, Game Freak and The Pokémon Company have periodically re-released older games with refreshed graphics and new features. These remakes not only keep the older games relevant but also provide The Pokémon Company with new content to sell while developing new generations of Pokémon games.
