So, Sony PSP Go was demonstrated at E3, where Haz Kirai (one of the directors of Sony) called the console “the worst protected secret.” The device is made in the slider form factor, has 3.8-inch screen, Bluetooth and Wi-Fi adapters, as well as 16 GB of internal memory. The new model is 40 per cent lighter than the original PSP-1000 probably due to a lack of UMD-drive. Games now are loaded from memory cards or Memory Stick Micro, or an online service PlayStation Network. 

Despite the fact that the UMD is no longer in use, the price of the console has not declined and is 249 dollars, and the sale will begin from October 1, in America and Europe, and from 1 November in Japan.
