DualShock can be used in lieu of Navigation Controller

Remember that rumor a couple years back of PS3 motion control gaming being based around a pull-apart DualShock 3? Well, perhaps it wasn't such a wild idea after all. No DualShock 3s have been harmed in the making of Move, but Joystiq has just confirmed that you can actually use the existing controller for Move gaming instead of springing for the Navigation Controller if you'd like. Obviously, you'll be one-handing the DualShock, not quite as comfortable as the Move's tiny, dedicated quasi-nunchuck, but it saves you $30 for your hassle. You'll only have access to the d-pad or four face buttons, depending on which side you choose, but interestingly, the Nav Controller's X and O buttons are redundant with the full Move wand, so hopefully this won't impact gameplay too greatly.
