Could you believe it? Today, on Smash Bros. Dojo Nintendo announced Wi-Fi capability for Super Smash Bros. Brawl.
As evidenced by the above photo there will be two modes: with friends or with anyone. "With friends" allows you to play against your registered friends and the battle records will be recorded. "With anyone" will randomly match you up with anyone in the world but no battle records are kept.
Prior to this announcement this game was expected to be the best selling Wii game to date. Now it just might end up as the best selling game ever (well, give it a few years).
