Well not all that much. Outside of the fact that it is a PS3 title, most likely the one shown in The Tester, the only other thing is that it sounds like a prequel to the franchise. Something that has been done already with the PSP game as well as the comic series published by Wildstorm. So, yea, that is happening.
Being one of the largest fans of the franchise one would think I would be creaming my pants for yet another God Of War title. I totally would be if it was a continuation of the main storyline but it looks like we are going to get another rehashed origin story. Maybe there will be something new, but I for one want to go forward not backwards. Hopefully there will be some new mechanics to the game play that will make that a moot point.
I guess we'll all find out as this is just a tease to an event where the Game Director will be spilling more details. The event will take place on the 30th of this month at 8am (PST) on the PlayStation Blog. I have a feeling that we will get more at E3, but maybe they will be able to explain a few more of the details.
In any instance, here's the teaser.
