SCEA has announced that the PSP version of Syphon Filter willbe taking advantage of the recently excpanded CPU speed of 333Mhz to deliver an experience that wasn't possible on the previous limit. They claim that they can now introduce Havok physics and larger environments as a result of the increased speed.

Hey everyone, I’m the technical director for SCEA’s Bend studio in Oregon, the developer of the Syphon Filter franchise. We’re working hard on the next chapter in the series, Syphon Filter: Logan’s Shadow for PSP, but I wanted to take some time to give a glimpse into how the PSP’s recently expanded processor speed (333MHz) will help us deliver a look and feel that wasn’t possible under the previous 266MHz limit.

For Syphon Filter: Dark Mirror, our concentration was developing an engine that could produce stunning PSP visuals, allowing for significant detail in the environments. For Logan’s Shadow, we naturally wanted to push the detail even further with our focus turning towards interactivity within those environments.

Now we have the ability to introduce Havok physics, water rendering/gameplay (as seen in the screenshot above), larger environments with significantly more interactive elements, and faster AI response times. In short, tapping into the full processor speed of PSP offers increased gameplay opportunities, while still providing the high production qualities you would expect after playing Dark Mirror.
