A post from Gematsu that detailed the features of Ultra Street Fighter II, an upcoming title for the Nintendo Switch. The article detailed online battles, and from the details given it looks like online matchmaking can be done through the console.

Quick Match – Searches for players able to fight without setting any conditions.

Custom Match – Set conditions and search for a player that you want to fight against.

Create Match – Create a lobby where you set the battle rules and such, and wait for the players that you want to fight against to join.

Friend Match – Searches for players that you can fight against now from your registered friends list.

As you can see from the above details, it sounds like you can do online matchmaking from the Nintendo Switch console, and must also mean that the app matchmaking is either an optional feature unlike the voice chat or it could’ve been a mistake by Reggie who confirmed this in a recent interview.
