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.
