Ehh, the "no wireless controller" thing turned about to be false, but the lack of HDMI, Wi-Fi, and Memory Stick reader still holds true.
The 500 dollar PS3 will not support wireless controllers. On top of that, it won't be able to display high definition pictures, it won't be WiFi-compatible, and Memory Stick functionality and memory expansion is not an option. Oh yeah, the radioactive spider-bitten Playstation 3 logo will not be in chrome lettering. The PS3 is not 500 dollars, folks. The PS3 is 600 dollars.
