Both cover options are below... Remember when you vote, the right choice is Iori.

Update - It seems that Ignition USA also posted a thread for choosing the Xbox 360 box art for King of Fighters XII. For the two choices (both also featuring Iori and Kyo), head over to Ignition USA's official forums. The two pieces use the same shots, but cropped in a different manner. Out of the two sets of pieces, it looks like Xbox 360 owners get the benefit of the better covers - but I still wouldn't be opposed to Iori gracing the cover of the PS3 version.
If you haven't had a chance to check out the forum links yet, some fans of the game have taken it upon themselves to also post some 'suggested' covers based on official King of Fighters XII artwork. There's definitely a vocal group out there that are opposed to the currently suggested shots...
