Posting to herald information pertaining to communication with Ruby, Sapphire, and Emerald:
As revealed
here and
here, you will be able to copy Pokémon in your party on any game between Ruby and Emerald onto Diamond and Pearl, but only once a day per cartridge. They will appear in the Safari Zone on Diamond and Pearl you won't have them straight away and will be rare depending on their rarity in the games from which they were transferred but the Park Ball required to catch them there will not fail.
