No, that controller exists. It was packaged in a blue package. The only place I know of that sold them was Walmart. I remember them being around only for a few weeks. Here is a post about them http://shoryuken.com/forum/index.php...-rumble.35164/ The model number is SCPH-10520 I suspect that Walmart pulled a GameQuestDirect on that one and they didn't sell. I am looking for one.
Edit: The article has one error, the ONLY difference is the motors. The layout is a common variant for both Dualshocks but most people don't disassemble the controllers side by side. These revision numbers are the letter present on the right side of the model number stamp.
