More information about the upcoming Pokémon Colosseum just keeps pouring in! In addition to being able to import Pokémon from Ruby and Silver and engaging in arena-style confrontations with other players, Pokémon Colosseum will feature a new 30-hour RPG mode in which players can catch 67 Pokémon from the Gold and Silver installments.
Pokémon Colosseum will not be able to connect with any of the Game Boy Color installments to the Pokémon series; it will, however, link directly to the GBA installments, including the upcoming Fire Red and Leaf Green. In addition to this, Colosseum will be compatible with Pokémon Box.
