I just checked on Dojo and it said Wi-Fi is in Brawl.There are two types.With freinds and with anyone.During With friend you can see there name icon etc.You can even send short messeges.You don't do anything exept taunt.when you taunt your charater will have a messege above him/her such as Want More and so on.During with anyone records will not be saved,names will not show,no messeges,etc.when the sceern is loading you can pratice with Sandbag.

I'm so happy I'm crying
