When the Dual Shock 3 was finally announced, a lot remained a mystery. While the latest firmware update provided rumble support, Sony has been notably quiet on whether it would work with PS2 games. We all assumed it would; I mean, it only makes sense, right?
Some intrepid European importers have solved that little mystery for us, though, as PSPSPS reports that their Dual Shock 3 controllers, hot off the Japanese production lines, have worked fine with providing rumble to titles such as Rez and Katamari Damacy using the 2.0 firmware upgrade. This was on a Japanese PS3, mind you, but previously Sony rep Kimberly Otzman told us that there wasn't any region-locking she was aware of.

While patches haven't been released for previously released PlayStation 3 titles, you should be able to at least get your shake on with PS2 titles and newer games that are designed with rumble in mind, like Ratchet & Clank Future.

That is, if you're willing to pay the import fees. Nothing like product rarity to promote opportunism.
