Sony Computer Entertainment America (SCEA) and Phil Harrison used to be quiet when it came to their plans and announcements for this year's Game Developers Conference in San Francisco. But now that the event is in full swing, they've relaxed a little and are  now more than happy to share what they've got in store for the future of the PS3 as well as the PSP.

Harrison's keynote presentation will take place on March 7 between 10:30 a.m. to 11.30 a.m. PST. Titled "Game 3.0: Developing and Creating for the 3rd Age of Videogames," the speech will focus on the role of the community, user-generated content, collaboration as well as commerce in the gaming industry. The official commented,

This is a very exciting time to be part of the game business. With advancements in technology and a shift in consumer trends, the development community has a great opportunity to create engaging new experiences in emergent entertainment content. This year we can expect to see a radical shift in creative game development that’s destined to drive our industry through the next decade or more.
