According to an Engadget Japan report, the recently announced PSP-3000 model will boast an LCD response time that is twice as fast compared to the current Slim model. That means there should be significantly less ghosting and color bleeding -- a widespread complaint with previous iterations of the hardware.
Additionally, the PSP-3000 LCD will feature five times the contrast ratio and double the color gamut. Looks like they've suckered me into buying a third PSP now :'(
