An anonymous reader writes "Sony has finally settled its longstanding legal dispute over infringement of Immersion Corporation's force feedback patents, which reportedly led to Sony's decision to remove rumble technology from the PS3 controller, by agreeing to pay Immersion at least $150.3 million in damages and royalties. The agreement presumably will result in rumble and perhaps other of Immersion's force-feedback technologies being incorporated in future Sony controllers. Microsoft previously settled a similar lawsuit brought by Immersion, but Sony hung on tenaciously despite complaints about its controller products and disappointing PS3 sales."
There's no guarantee that the tech will show up in the Sixaxis controller, of course. After all, rumble is a 'last-gen' feature
