PSPFanboy.com were lucky enough to get a hands on look at the Japanese Peripheral, that adds TV functionality to the PSP. Unfortunately this is only to be released in Japan, Why? Apperently Sony stated that overhead costs would make this unit too costly for overseas markets. I think it´s a big mistake to not release this worldwide. I´m sure there would be demand for it. Like the old game gear Tv tuner (remember that?). I wouldn´t mind one myself if it was released and would receive DVB digital signal. This tuner only works in Japan, with the 1seg standard there. Its 100% useless unless you live or plan to visit Japan and wish to have TV on your PSP Slim.
