Bogus or not bogus?: Not bogus that a rumble-enabled Dual Shock 3 is coming. GameSpot has learned from a source close to Sony that the company is definitely working on a force-feedback-equipped controller for release in the "coming months." However, as of press time, Sony higher-ups were still apparently debating whether or not to unveil the device at TGS--though a less appropriate venue doesn't spring to mind. It was also unclear if the Dual Shock 3 would have the Sixaxis' tilt-sensing technology, or whether the functionality had been abandoned altogether.
