Remember all that talk a while back about some huge surprise that had yet to be revealed for Metal Gear Solid Peace Walker? It seems that it still hasn't been revealed.

Kojima Productions PR manager Jiro Oishi alludes to this surprise feature in a recent post at the Kojima Productions blog. After noting that he's touring the country to convey the charms of Peace Walker's co-op play, he writes: "However, in truth, there's another ultimate charm outside of co-op play hidden in PW." This is something that will be introduced over time.

Back in late October, Hideo Kojima himself made a post about a big Peace Walker surprise that would make people rush out to buy a PSP. As far as I know, there hasn't been any such surprise announced for the game since then, so it's likely that Oishi and Kojima are speaking about the same feature.
