At a GDC lecture Haden Blackman, the project lead on The Force Unleashed, stated that Lucasarts has now learned a valuable lesson from its development of the game. All future multiplatform projects will prioritize development on the PS3 before being ported over to the 360. This is a direct result of problems and delays during the development of The Force Unleashed caused by trying to port the 360 version to the PS3. The game is now, thankfully, on track, despite these delays.
A live demo of The Force Unleashed was also shown and, from what we've heard, it looks absolutely stunning. We can't wait for its release this summer.
