Don't worry. Your youtube friend is completely mistaken.

For one thing, it hasn't been confirmed that there will even be an SAO 3.

If SAO 3 is produced, though, it will be about an arc called "Project Alicization." I won't spoil the details for you, but there will be swords involved. There's no "punch art," as far as I'm aware.

If you want spoilers, they're on the wiki here: http://swordartonline.wikia.com/wiki/Alicization_Arc

Side Note: My apologies to the wiki's higher-ups if it's bad manners for a random, anonymous user to answer questions like this, or if I've somehow given misinformation. I just thought I'd help, if I could.
