Update 6/2: It has been reported that the PSP Go will launch on October 1 with price of $249.

With Sony’s E3 press conference only a few days away, June’s edition of video magazine Qore has leaked online. The video shows an interview with John Koller, Sony’s director of hardware where he reveals some of the PSP Go’s primary specifications while the interview host toys with the device and asks an ordinary series of questions.

As speculated, the PSP Go will feature a sliding form factor, and the UMD drive is no more. Koller says that the main differences between the Go and the PSP 3000 are the integrated 16GB of flash memory, Bluetooth support and naturally, the emphasis on improved portability, being 43% lighter and having all-digital content. Other details include a 3.8” display, a Memory Stick Micro slot, complete PlayStation Network support, PS3 integration as well as new Gran Turismo, Little Big Planet and Metal Gear Solid entries.

Koller added that Sony’s latest handheld is not going to replace the PSP 3000, so if you prefer to purchase tangible content, the door remains open. If the video (link) didn't quench your thirst, there is a series of press images here. Pricing for the PSP Go has not been disclosed yet, but it is expected to be available this fall.
