.. a mysterious question-mark. Kojima formally revealed the first trailer of Metal Gear Solid: Rising during Microsoft's press conference last night and it looked incredible. Alas, it appears the show is far from over for Kojima-san, who will probably have one reveal left in him.
While it's difficult to speculate based on a black box and a question mark, there does appear to be a sickle hidden in the empty space on Kojima Productions' website. Make of it what you will.
The question remains - where will he make this announcement. Kojima could have something for Nintendo's new 3DS in the works, he could be saving an announcement for the Konami press conference, or he could show up at Sony's event this evening.
We'll have to wait and see.
