Pokemon Sword and Shield come out November 15th.
And here is an excerpt of a feature:
“One of the features available on the Y-Comm menu is the Surprise Trade. Select a Pokémon from your Boxes that you’re willing to trade, and that’s it! A trading partner will automatically be found as you continue on your adventure!”
So basically a better version of wonder trade.
“Membership in the Nintendo Switch Online (paid) service is required to participate in Link Trades and Link Battles using the internet. There’s no need to set up a membership for local communication use.”
That basically just kills it. As expected.
