At Sony's E3 conference we got a little update on four of the games revealed at the PS4 unveiling earlier this year. Killzone: Shadow Fall, Driveclub, Infamous: Second Son and Knack were all on display. There were short demos/trailers for each, and some release details: Killzone: Shadow Fall, Driveclub and Knack are all to be released at launch, whereas Infamous: Second Son is coming in Q1, 2014.
