I have had my Jap import for several months now and it does occasionally crash (just freezes - touching power button for five secs does a reset), although tbh it's only happened probably about 4 times in about three months. I initially thought it there was something wrong, but then after getting the 360 I get the same kind of problems about just as often (which is very rare) so I thought it was just down to the fact that modern consoles are probably more like PC's than consoles of old, with their OS etc, and my PC crashes occasionally too - maybe that's just the way it is now?
