The redesigned PSP makes games load faster. But, how? In a private demonstration with Joystiq, John Koller explained that the new PSP includes more than just good looks. The redesigned system also includes more RAM, which is used to increase the load speed of upcoming PSP titles. In addition, the system has much more efficient battery life. Koller promised between 8 to 10 hours of battery life in the new system, a seeming impossibility when remembering the original design.
