DualShock 3 rumble works with PS2 games

Even if your PS3 doesn't work with PS2 games, apparently your fancy, imported DualShock 3 controller will. And that doesn't just include letting you spin two (count 'em!) two analog sticks while you're catching monkeys with a net. No, friends, you'll also be able to feel the visceral thrill of rumbling as you whack the monkeys with your stun club. ... Or, you know, play other PS2 games that don't involve catching monkeys. The DualShock 3's rumbling abilities with PS2 games, which only a few would have noticed by now, was apparently added by the PS3's 2.0 firmware.

So the DualShock 3 is the newest gen of a next-gen peripheral now reaching back through time to accommodate a last-gen feature on last-gen games. But the only PS3s that support it will be those that play last-gen games, a feature that itself has become last-gen. We've honestly lost count of the layers of irony. Help us out here, Alanis.
