2. Metal Gear Solid: Ground Zeroes
Having only shown up for the first time at the Penny Arcade Expo last year, it's unlikely MGS Ground Zeroes will be out in time for 2013. Granted, it looked in pretty solid shape in the gameplay trailer we were treated to, but it looked far too good for current generation hardware. With that in mind, a 2014 launch alongside the PS4 and/or Xbox 720 makes more sense.
