At its presentation at this week's E3 Expo in Santa Monica, Sony took the wraps off a redesigned PlayStation Portable (PSP) which is 33 percent lighter, 19 percent thinner, and sports a high quality video output so users can hook the unit to an external monitor or display to view photos, videos, or movies. On the surface, the new PSP doesn't look dramatically different from its current incarnation, and in some ways the redesign fails to meet some gamers' hopes for a "PSP 2" with dramatically enhanced capabilities.
