Not a whole extra month. 10th - 9th with February's lack of days at the end.
Can an almost month of fine-tuning hurt? Seriously, the impatience, the whining and the "**** I WILL KILL SAKURAI" are, well... immature. I want it noooow, daddy. I want it!!
Had Melee been delayed a year, even, we wouldn't have cared by this point in time. Sooner or later it'll be six years after Brawl as well, and no one will remember the delays.
