OR/AS retained exactly the same in-game trades from Ruby/Sapphire, so I'm expecting the same D/P/Pt trades to be retained for BD/SP. Cue the rage surrounding Mindy and her infamous Everstone-holding Haunter!
True but the HeartGold and SoulSilver trades did add some more trades than the Gold and silver trades. Let's go game trades were different to most other Kanto trades so its not impossible for there to be further trades added or significant changes.
