According to the rumors section in the latest issue of PlayStation: The Official Magazine, Guerrilla Games are already hard at work on developing Killzone 3 as well as Insomniac with Resistance 3. Treyarch is also mentioned to be developing a Call of Duty: World at War sequel. They’re mentioned as “secret games of 2010.”
“Insider slips reveal three big names you can already pencil for the next year,” the magazine reads, “Killzone 3 is reportedly deep in development, Insomniac’s Full Moon Show podcast hints at a project we can only conclude is Resistance 3, and a Treyarch employee’s online mentions a Call of Duty: World at World sequel.”
Take all of this with a grain of salt, considering Killzone 2 took nearly four years to develop, we doubt the third installment would release so shortly after the second. Resistance 3 seems to be on point though, considering that leaked banner for the new alien Sony flick.
