PS3 Slim Same Features, But HDD Changable ?

May be...

There isn't anything that suggest it isn't changable. And only a 34% reduction in size? I don't think that would require a different type of hard drive.

according to that official picture: http://www.blogcdn.com/www.engadget.com/… , there appears to be a removable plate that gives access to the HDD

Probably the same way as the fat PS3. Screw the side open, blah, blah, blah...Not all simple and easy like the Xbox.

IT's been moved to the front.

Opposite side of the USB ports.
