An anonymous industry source has indicated to Videogamer.com that Killzone 4 is currently being prepped by Guerrilla Games for a 2013 release, and possibly as a PlayStation 4 launch window title.
Killzone 4 IS most definitely in the works (Guerrilla Games confirmed this in 2011), and while its target console is still up-in-the-air, a 2013 release on PS4 makes sense; our own sources confirmed to us that PlayStation 4 will launch this November. Much like Killzone 2 redefined visual fidelity with an impossibly good-looking trailer at E3 2006, we expect that Killzone 4 will astound us and raise internet cries of doubt.
Those cries of doubt will be silenced when, much like Killzone 2 before it, the final product will actually look better than pre-release trailers.
Stay tuned to PSU.com for all things Killzone and PlayStation 4, and check out our predictions for the PS4 reveal event on February 20.
