Protagonist Kratos was listed among other PlayStation brand characters, such as Resistance's Nathan Hale as Metal Gear Solid's Solid Snake, that will be highlighted during today's festivities.

While Metal Gear Solid 4 arrived on PlayStation 3 last month, a new Resistance title is due out this fall. The last God of War game hit PSP earlier this year, with a tease that God of War PS3 was "coming soon."

"This is the most stressful event you can ever imagine," Tretton commented.

Update: Sony has now unveiled God of War 3.
