Just last week Sony made available for pre-order Warframe and PS4 exclusive Knack.
A link in the blog sends gamers to the Sony Entertainment Network webpage, where customers can pre-order the games, though only Knack and Warframe weren't available for purchase at the time of publication.
The Hardened Edition of Call of Duty: Ghosts and the Assassin’s Creed 4 Gold Edition will also be available for pre-order, and all four games will come with pre-order bonuses. Click the link above for details.
Sony said those who pre-order the PS3 versions of Call of Duty: Ghosts, Assassin’s Creed 4 or Battlefield 4 can upgrade to the PS4 digital version for just $10, though the offer’s only for a limited time.
Also, those who buy a season pass for the PS3 version of the three games will be able to download the PS4 digital version for free as long as they buy the season pass by May 31.
