As you may or may not have noticed, with all or most of the pics of the PS3 and its controllers at the bottom it said something along the lines as "subject to change".

Think about it, there is a long time before it's launch and they could possibly due anything they wanted to the system and controllers. It was just a the unveiling of a system, nothing said that what you saw was official.

"why I've gotta be one of the cool kids just to walk by/
- without being tripped, thrown down on the ground and kicked/
Insulting me for no reason, I was treated like shit/
The teachers let it happen/
I've even seen some of them teachers laughing/
That's why I had a smile on my face when I started blastin/" - Ill Bill - The Anatomy of a School Shooting
