Well, it's either The Order, Knack, or Killzone. Bundling an internally developed game technically means no lost profit, since they have to pay no fee to any company or any of the profit to a third party. I would assume that they have to pay some small fee to independent publishers when they make a FIFA or COD bundle. It seems like a no brainer to entice new buyers. It wouldn't make sense to include one of two 18 month old games in a bundle with two, more popular new releases.
