Eurogamer got a chance to take a look at Sony's latest hardware revision for the PSP
. Their overall impression of the new model is positive, finding that a redesigned screen offers noticeably better graphics and higher brightness without affecting battery life. They also say the button pads may be slightly different, and the unit comes with useful firmware upgrades.
"Elsewhere, our side-by-side comparison of the current PSP/PSP-2000 firmware, 4.05, and the new 4.20 firmware on the PSP-3000 reveals a 'USB Auto-Connect' option, which promises to automatically switch the handheld to USB mode when a cable is connected. It will do this from anywhere on the XMB, but it won't interrupt gameplay. ... The new-model PSP also allows you to play games on a TV by hooking it up with a special adapter (sold separately) and a composite cable, whereas the old one would only allow composite cables to display video, with gaming reserved for component output."
