Ahead of the official Sony E3 2009 press event which is when we’re meant to receive Sony’s word. It seems plans to continue its podium mark in the handheld gaming device market with Playstation have been leaked in advance. The PSP Go shouldn’t be considered as a replacement for the PSP 3000, but instead, a companion.

While specs are sketchy, you can check out what we do know so far after the jump. Images have revealed that the PSP Go will be slider based, completely UMD-less and will have an internal memory capacity of 16GB.

Here are the specs that are being discussed on the web at this point, though none are yet officially confirmed.

• 3.8-inch display (resolution is undisclosed)
• 43 percent lighter than the PSP-3000
• 16GB of Flash storage
• Bluetooth built-in; supports handset tethering and BT headsets
• No UMD drive
• Memory Stick Micro slot
• New Gran Turismo, Little Big Planet and new Metal Gear Solid (!) on the way
• Full PlayStation Network support (movie and TV rentals / purchases)
• Integration with PlayStation 3 (works the same as the PSP-3000 does)
• Sony views each of its products as “10-year lifecycle products,” so the PSP “needs to live on.”
