Sony recently confirmed with 1UP that PlayStation 3 will not support force feedback, a technology that is often integrated into racing wheel peripherals. The explanation was vague: "All PS3 games are programmed for the Sixaxis which doesn't have force feedback, therefore the force feedback in the wheels won't be recognized."
Perhaps Sony misspoke. There aren't any console gamepads that support the type of force feedback technology built into many top-line racing wheels, so when this feature is enabled in racing games, it's an additional programming step that only benefits players using an appropriate racing wheel -- it simply doesn't matter that Sixaxis lacks full force feedback (or even simple rumble feedback). If Sony is actively dissuading developers from coding in force feedback support for racing wheels compatible with PS3, it has nothing to do with what Sixaxis lacks ... then again, it might have everything to do with what Sixaxis lacks.
If indeed Immersion technologies like rumble and force feedback are never be supported by Sony's new console it's almost certainly the result of the 2003 lawsuit brought against Sony by Immersion, and the judge's denial of Sony's subsequent appeal.
