I want to know the answer to the following question:
At what event at the Tokyo Game Show was the DualShock 3 first announced?
All the background I'm provided with is that "At its press conference at the 2007 Tokyo Game Show, Sony announced DualShock 3 (trademarked DUALSHOCK 3), a PlayStation 3 controller with the same function and design as Sixaxis, but with vibration capability included.". Is that enough to answer the question?
