Ars Technica is reporting that a UMD-less PSP-Go! (aka PSP-4000) will be getting some spotlight at E3 2009. These are the same people that reliably claimed such rumors as the RE5, Halo 3, and Fable 2 bundle for the Xbox 360. Speculation of Sony pushing out a UMD-less model has been running wild ever since Patapon 2 was released as a download-only game. The insider claims that the system will also be lighter, have a lower power consumption (meaning higher battery life), and possibly even a lower price.

The Playstation 3 Slim will likely not be announced at E3 this year, mostly due to the thousands of regular PS3’s still hanging out on store shelves. Most likely Sony will make their move quietly, announcing the PS3 Slim right before it hits store shelves.  According to what everyone is calling the “mole”, that should be August or September, right in time for holiday 2009. The image above is a supposed leaked version of the system.

1up claims to have “reliable sources” with knowledge of the next generation Playstation Portable. Here are a few of the highlights:

• It will be revealed at E3 09, and released this fall.
• The system will scrap the UMD drive in favor of an internal flash drive.
• It’s name will supposedly be “PSP Go!” (Which is speculated because of all the “Go!” accessories released in Europe.
• Japan gets the system in September, US gets in late October or early November.
• Sony will have over 100 classic and new PSP titles available for download at launch.
• Sliding screen design similar to the mock-up above. No second analog stick.
• The “PSP Go!” has two separate models, 8GB and 16GB.
• Possible 800×480 touch screen and built in camera.
• Grand Turismo Mobile is speculated to be the poster-child launch title.

Remember these are just rumors, however 1up tends to be a trusted source of information, and many of these claims have surfaced before. We will undoubtably see at this years E3. You can read the full article over at 1up.
