I think people who break street date so it out if foolishness more than anything.
Unfortunately, we will have to remain strong these few remaining days when it comes to spoilers. People will spoil mostly because people want to know so badly. Case in point: three years ago when Pokemon X & Y was the big thing, some nobody with a Pinterest account got ahold of an early copy in Canada. He started posting things about the game and instantly he went from 40 followers to almost 10,000! Eventually he got "Nintendo'd" and he took down everything related to the game and went back to having 40 followers. But even with a lesser known game like KOF there will be people who will eat up any morsel of information.
On another note, has anyone read the team stories yet? I liked them a lot.
