Sony Japan's just outed three newly styled S Series Walkmans for the Disney fanatic. That's right, Mickey & Minnie Mouse can now be found gracing the back of your PMP -- if that's what you're into, of course. The S640 and S740 models can be chosen in their wide variety of hues, then emblazoned with one of the three designs featuring Mickey, Minnie, or the pair together. Unfortunately for us, the engraving of Disney characters on Walkmans remains an underground, unofficial pastime: the Disney S Series Walkmans are available only in Japan at this time.
