Sony has very recently denied that it has added rumble support to the PS3 controller. Although a Spokesperson has confirmed that developers are now receiving PS3 controllers with better motion sensing functions. Sony say this is all just the usual evolution of controllers making minor imporvements as time goes by.

"We have not added rumble [to PS3], and have no announcements regarding this feature," said Dave Karraker, Sony's director of corporate communications.

Karraker did confirm that developers are receiving better motion-sensing controllers, though he downplayed the news.

"From time to time, we make minor enhancements to the controllers for our platforms," he said. "We recently sent out to the development community some new prototypes that have a slightly enhanced sensitivity for the analog sticks and the motion sensing within the Sixaxis controller.

"This is not a new controller, but is part of the normal development and evolution of controllers," he maintained.
