Sony Japan has said there is going to be a Gold PSP but it is only going to be available in Japan. It will be the same price as a standard PSP of about $175 which includes a battery and ac-adaptor. The addition of the gold PSP brings the total number of different colours to six - black, white, silver, blue, pink and gold.
