I don't understand why they didn't have pictures of Raiden from MGS2, or pictures of Big Boss, Snake, Old Snake, Ocolot, and all of the characters from the long Metal Gear History.
But no, it's just a bunch of boring and lame different poses of Raiden in a white background.
Someone really screwed up here.
Raiden's game isn't out yet and I believe they didn't want to spoil anything about it just yet. It's the same reason Dante's costumes are just varying levels of shirtlessness instead of actual costumes.
I'm sure 2K and Irrational Games don't want to spoil Bioshock Infinite either, but they made a much bigger effort.
