Sony has confirmed that Phil Harrison will be showing off new services and games for PS3 when he delivers his keynote address on Wednesday, 7th March, at 18:30 GMT.
We'll be bringing you Live Text from the presentation as it happens, so make sure you're here for kick off.
His speech will cover the key components of what Sony is calling "the third era of videogames", focusing on community, user-generated content, collaboration and commerce.
Sony was unavailable to comment on what the games and services might be, though speculation about PS3 "Home", an avatar-based achievement system for the community, continues.
"This is a very exciting time to be part of the game development community," promises Harrison, president of worldwide studios, Sony Computer Entertainment. "I believe we're at the threshold of a new era in creative game development that’s destined to drive our industry growth through the next decade or more."
Following the speech, Sony's booth on the GDC show floor will be demonstrating downloadable PlayStation 3 titles, as well as showcasing the versatility of Unreal Engine 3 - which will be powering shooters as well as online adventures, we're told.
GDC is primarily for developers, of course, so Sony will be showing off plenty of stuff that's of more interest to people who make games than people who play them - creating content for PS3 using Linux will be a hot topic, as will swanky new graphics software, physics and analysis tools.
Something for everyone then. Just make sure you're here tomorrow at 18:30 to catch the action as it happens.
