A couple weeks ago, Sony quietly added both PS4 launch titles Knack and Warframe to the PlayStation Store for pre-order. Today, with the PlayStation Store update, Sony will be adding four more titles—the PS4's most anticipated launch titles—up for pre-order on PSN.
Starting later today, Call of Duty: Ghosts, Call of Duty: Ghosts Digital Hardened Edition, Assassin's Creed IV: Black Flag, Assassin's Creed IV: Black Flag Gold Edition, Battlefield 4, and Killzone: Shadow Fall will all be available for pre-order. Each game pre-order also comes with digital incentive DLC.
Presumably, once you've pre-ordered these games on your PS3 or online, they'll be available in your download queue on your PS4 once you've plugged it in and fired it up for the first time.
Will you consider pre-ordering through PSN? Or are you sticking to retail for launch titles?
