Why the hell are we talking about when seasons are in Sweden or Italy or whatever? Who cares?

This is a Japanese game, made by a Japanese company. If they make a global announcement regarding a seasonal release, it should be automatically assumed that they're talking about seasons in Japan, unless otherwise stated.

Do you think the Australians saw the "fall" announcement and then were saying "hurr durr, but fall is already almost over this year, durr"?
