Of course this is PURE speculation, but recent job postings on the official PlayStation Careers site may hint to what is to come. There have been several job listings for Santa Monica studios, the team known mostly for its creation of the God of War series. The job listings include the following positions:

• Senior Tools/Technology Programmer (God of War Team)
• Senior Online Programmer (God of War Team)
• Senior Graphics/ Technology Programmer (God of War Team)
• Senior Gameplay/Generalist Programmer (God of War Team)

Here is a screen cap just for a little proofing:

Note each title did say “God of War Team.” Could this mean another sequel on its way for the highly popular God of War series? *spoiler* The ending of the PS3 exclusive God of War III led many gamers to speculate that another title was on its way due to Kratos’ death and then his body vanishing.*spoiler end* PSP owners did get God of War: Ghost of Sparta in the Fall of 2010, however this title was a prequel to the series. So questions still remained unanswered.

No doubt, God of War is not the only title that Santa Monica studios is known for. They also created the highly addictive Fat Princess games on the PSN, Warhawk, and flow to name a few. On that same note, could this finally be a sequel to the PS3 staple Warhawk? Fans have been calling for “Starhawk” and devs have hinted in the past that it could very well be on its way.  Could this be another title? Possibly a new IP? With the new NGP announced, could this be a God of War NGP project?

after god of war 3's ending id be surprized if they didnt make another title

I'm calling NGP title.

NGP got a lot of good news recently, but what it needs now are games. The 3DS lineup is huge, not only in numbers, but also in big IP's. So far we "only" got Uncharted, Killzone, LittleBigPlanet and Monster Hunter as big names. A God of War title would raise the lineup considerably.

New IP! For NGP! PLEASE!

One of my fave teams....I really would like to see a new IP from them or their take on an older IP..and I'm a HUGE GOW fan.I just know these guys make some amazing games and I will find a NeW Ip more exciting...make it for NGP too and make that already nice looking (yeah even in a 10 or so title line up, we have a UC, KZ and R and GRAVITY DAZE) even better!

There's no way they aren't working on a new God of War after the ending of GoW3.

And besides, the userbase is pretty big on the PS3 so it would be a lost opportunity not to release a new one. The franchise is very versatile. They can make a story around pretty much anything they want.

Could be an NGP game, could be GoW4. Either way I'm interested. 

i assume it will be a new God of War revamp on new PSP

I'm one of the biggest GoW fans in the world, so yeah... I'm excited

its most likely the god of war game for the NGP

I want Sony santa moniac to make a new IP first before doing another God of war game.

Weren't they rumored to be making a RPG?
