Super Smash Bros Brawl it would seem has gotten delayed by Nintendo once again moving from February to March. They released an official notice on their website stating:

"Due to delays in the completion of Super Smash Bros. Brawl, we’ve had to change the release date of the game to Sunday, March 9th.

I deeply apologize to the people who have looked forward to playing the game for so long and ask that you hold on just a little longer. Thank you for your patience."

Let's hope they have all the kinks completely removed then and the game polished to the highest possible quality.
