Sony could be aiming to have Killzone 3 ready for release by April 2011.

According to a report by 1UP, Guerrilla's PlayStation exclusive FPS could be going head-to-head with Epic Games' Xbox shooter.

Earlier this month, we reported that sources said Killzone 3 would be in 3D and make use of PlayStation Move but also that it would be coming out in time for Christmas.

Since then rumours have been flying about the release of Gears of War 3 in April, with Epic VP Mark Rein saying the company had no plans to release anything this year and boss Mike Capps hinting at a new game announcement at E3.
