Apparently the PlayStation 3's Sixaxis controller could have rumble in the very near future. Game developer blog, Innerbits, can confirm two independent sources within Sony stating that the company has been "working on prototypes for for several months". The only thing stopping you getting white-finger while playing the next version of Motor Storm (the upgrade to which has been delayed, by the way) is, apparently, a 'battery life issue'.

According to Innerbits, "Officially, the corporate line is still “no comment”. Unofficially, Sony is facing some difficulties with battery life; i.e. Between the rumble and the wireless support, the batteries are draining too fast to be acceptable for consumers."

It's also being reported that (despite Sony's Phil Harrison calling rumble, 'last-gen', and the company complaining that Immersion's rumble technology would interfere with the motion sensitivity), "...no mention of the rumble having an adverse affect on the motion sensitivity".

This all echoes statements made by Sony Computer Entertainment (America) C.E.O., Jack Tretton, in March when he alluded to changes being made to the PS3s controllers.

Where all of this leaves companies such as Splitfish and its rumbling controller, or Hori with its Famitsu-rumoured rumbler is open to question.
