Sony has announced that digital pre-orders are open now for some PlayStation 4 titles. Each of the four titles comes with a bonus.

Killzone: Shadow Fall will come with The Shadow Pack, which includes the soundtrack, a skin for the in-game OWL drone, and a "multiplayer spotlight move." Call of Duty: Ghosts (in standard or hardened editions) comes with the Free Fall map.

Assassin's Creed IV: Black Flag (in standard or gold edition) comes with an Aveline ship figurehead. Finally, Battlefield 4 comes with the China Rising expansion pack.

As a reminder, Assassin's Creed IV, Battlefield 4, and Call of Duty: Ghosts are eligible for the $10 upgrade plan. If you purchase one of these titles on PlayStation 3 (digitally or via retail), you can upgrade to the PlayStation 4 digital version for $10 more. For more on how that works, read our previous coverage.

Our Take
I love the idea of digital pre-orders, assuming that purchasers will be able to pre-load content once consoles are in-hand. Next-generation titles are likely to be quite large. My only hesitation about digital alongside the console launch is the immense server traffic that could pop up. If Sony (and a week later Microsoft) weather the storm and are able to deliver data and get people playing quickly, it will go a long way to allaying my fears about these enormous game downloads.
