well almost every console in the world is released here later than oversea's so i don't see how that would of made a difference at all.
PSX was launched in 94 in japan, 95 in australia, ps2 was released march 2000 japan, and october 2000 in australia,
gamecube was launched september off the top of my head in japan and march the following year here,
psp was launched in november in japan and mid the next year over here.
So i don't see where you are going with that.
