Jack Tretton, president and CEO of Sony, took the stage today at Sony's E3 press conference, and started off with some jokes, telling the audience that he believes Sony is the leader in many things, including leaked content. All the same, the PSP Go (or the "Worst Kept Secret" as they nicknamed it) got it's formal debut, listing off its technical specs, price tag, and release date.

As Sony describes it, the PSP Go is specifically designed for a digital lifestyle, meant for those consumers who wish to live completely digitally. Like earlier reports, the PSP Go will not incorporate UMD's, opting for downloadable content for everything. The product will be released in the autumn on October 1st in the US, going for a price tag of US$249 (around £150). UK pricing and availability hasn't been announced.

Along with being smaller, lighter, having 16GB of internal flash memory, built in wi-fi and bluetooth, the PSP Go will incorporate Media Go, which will replace media manager in helping you consume all forms of media on the PSP including games, video and music. Playstation's video delivery service will also be available for the PSP Go, allowing users to have what they call "Entertainment everywhere."

Sony was clear on letting people know that the PSP Go will not replace the PSP 3000, but will work as another option for those who prefer a more digital lifestyle. They are still going to produce UMD's and release every game as either downloadable or in UMD form.
