A little more than a week before the games launched, Nintendo put out a news update for Pokemon Brilliant Diamond and Shining Pearl that described a day-one patch for both titles as well as some of the plans that the publisher has in store for them. Among these plans was the introduction of the wildly popular Global Wonder Station, an area originally introduced in Pokemon X and Y that allowed trainers to receive random Pokemon from trades with people all over the world through a mechanic known as "Wonder Trade."
Unfortunately, while Nintendo will be replacing Diamond and Pearl's Global Trade Station with the Global Wonder Station — bringing the area back after leaving it absent from Pokemon Sword and Shield — the Wonder Station itself will not include the Wonder Trade mechanic upon arrival. Instead, players will only be able to Link Trade through the area — Link Trading being the equivalent of regular trading, where each trainer specifically selects the Pokemon they want to trade for.
That said, it's still very much possible for Wonder Trade to come to Pokemon Brilliant Diamond and Shining Pearl. Like the Global Wonder Station itself, Nintendo likely plans to include Wonder Trade in a future update, but unlike the Station, the publisher needs more time to get the mechanic working. After all, it wouldn't make much sense for Nintendo to bring back the area known for the mechanic if it had no intention of bringing back the mechanic itself.
Exactly when Wonder Trade will arrive remains a mystery, as it's still unclear when the Global Wonder Station itself will make an appearance. The news update Nintendo put out only relays that the update for it is coming; it doesn't specify when, and since its release, Nintendo hasn't revealed anything more about its plans. A guess would place it sometime around late December or early January, with the Wonder Station coming early or mid-December.
In the meantime, players can spend their hours filling out their Pokedex with the features introduced in Brilliant Diamond and Shining Pearl's day-one patch, such as Ramanas Park, an area available to trainers after they become the Sinnoh region's champion. The park allows them to catch legendary and mythical Pokemon that aren't usually available in the Sinnoh region, such as Rayquaza and the original Regi trio. Afterward's there's no harm in catching a bunch of Bidoof to prepare the randomness of Wonder Trade.
Pokemon Brilliant Diamond and Shining Pearl are available now on Nintendo Switch.
