Sony and Immersion have settled their long-faught lawsuit regarding the rumble technology Sony uses in its controllers. The deal reached between Sony and Immersion would open a door allowing Sony to add this technology to the Sixaxis controllers for the PS3. Immersion's CEO has already stated that a technical proposal for rumble PS3 controllers will be made very soon.
Immersion originally sued Sony for $97.2 million for patent infringement, which Sony quickly appealed. To continue selling PS2 accessories, Sony paid Immersion $30.6 million, but left the vibrating feature out of the PS3 controller claiming that the rumble feature would not work with a motion sensing controller, which may or may not be true (but sounds like a lot of BS to me). So what happens if they do re-release the Sixaxis?
