This game seems to be a bit undervalued. The previews for the game seem generally positive and the game will likely be one of the stand out titles when it is released, or will have much less competition. The Xbox360 version will sell more, but it won't completely eliminate sales for the PS3, much as CoD4 for the PS3 still sold despite the XBox360 version doing incredibly. Due to this around 60DKP seems like a better price.
