If you want to experience rumble with your PS3 games as soon as possible, you're going to have to go on a quest of sorts. First, time travel into next month (or wait a couple of weeks) and import a DualShock 3 from Japan. Next, you're going to need the PS3's new firmware, 1.94, but sadly, it isn't available for download yet.
But don't be deterred. Shacknews is reporting that if you pick up Ratchet and Clank Future: Tools of Destruction (the first retail game with built-in rumble support) you'll be able to find 1.94 right there on the disc. Imagine the convenience. Now, unless you have obsessive compulsive disorder, we have no idea why you'd need the firmware weeks before the controller's even out. But at least we know a certain former Double Dare host is going to sleep well tonight.
