It's been confirmed that the latest PlayStation 3 firmware update (to version 1.94) adds support for the forthcoming rumble-enabled DualShock 3 - though it's not available for download yet.
The update is being bundled with Ratchet and Clank Future: Tools of Destruction (the first PS3 game to support rumble), which is due to arrive in the shops on November 9.
Those of us who already have copies of the game (a bit of willy waving there for you) will know that by pressing the PS button, the DualShock 3's vibration can be toggled on and off from the in-game controller setting menu. Riveting stuff.
Sony's planning to ship out the new pad in Japan this November, with a US and European release bizarrely planned for next year.
Don't wait around for your rumble; import a controller, we say.
