Killzone: Shadowfall, DriveClub and Knack will be PlayStation 4 launch titles

Sony's Shuhei Yoshida confirmed the news on stage during the firm's pre-E3 press briefing today.

Yoshida also confirmed that Sucker Punch Productions' open-world action sequel Infamous: Second Son will be released in Q1 2014.

Killzone: Shadowfall, DriveClub and Knack were first announced at Sony's PS4 reveal event in February.

DriveClub, Evolution Studios' PS4 exclusive, is a multiplayer-focused next-gen racer in which players can compete in both real time and asychronously.

Knack, from Sony Japan Studio, was described as an action platformer that "invites players to wield fantastic powers and discover a unique and vibrant world".
