Killzone looks to be playing catch-up

Guerilla Games has announced that a sequel to Killzone is in the works (and not for PS3).  The first game has just now entered beta testing, but it looks like Guerilla Games and Sony are eager to catch-up with Microsoft's breadwinner, Halo.  After all, the big hype surrounding Killzone is that it's going to be the 'Halo-killer' Sony has hoped for ever since, yes, 2001.  Maybe they finally realized that besting a game that's three years old is not much better than me beating my grandfather in a race.  And with Halo 2 around the corner, you can bet they're going to need that head start.
