According to the Smash Bros. forums and gonintendo, Super Smash Bros. Brawl has gone gold and is ready for mass production!  This seems about the right time since the Japanese launch is less than a month away (January 24).

I can’t wait for the Japanese launch because we’ll get a TON of information about characters, stages, and everything! —-although I hope there aren’t too many spoilers released on the ‘net at that time :S
