A listing is now on Amazon.com for the online game code for Metal Gear Rising: Revengeance, the upcoming Windows edition of the stealth/action sequel (thanks DSoGaming). We recently learned this is due "any day now," and the listing shows a January 9, 2014 release date, which is certainly "any day," though not necessarily "now." The listing also includes the following system specs:
