Sony will package together the three major Killzone games for release in trilogy form, a new product listing by Amazon France suggests.A game page for the Killzone Trilogy pack was spotted on the French retailer (thanks,TheSixthAxis) for release on 24th October.It was priced €59.99 - that's about £47.Amazon France previously leaked the existance of Call of Duty: Black Ops 2 and Sony's own Ratchet and Clank Trilogy.Killzone is now one of the few franchises Sony has yet to turn into some kind of collection pack.We've already seen a Sly Trilogy, Jak and Daxter Trilogy, Resistance Trilogy and Ratchet and Clank Trilogy.Third-parties have also been getting in on the action too, with Splinter Cell and Tomb Raidertrilogy collections, among others. http://www.amazon.fr/
