Yes, there are natural disasters worldwide, but the event was canceled BEFORE somebody knew about Hurricane Florence, so what do you want to tell me?
Nintendo even stated that they cancel the event because of their typhoon.
Several problems. First off, the event was cancelled over a earthquake; creating a devastating landslide. They did not mention the typhoon. Second, it's not about a event being cancelled before knowing tragedy would strike. The aftermath of a earthquake was sudden and could not be predicted by any means. Even when measured, it would still be impossible to warn people or predict that a large amount of soil would come tumbling down towards their homes.
But with this hurricane, we know it's coming and we know when it's going to make landfall. People are going to lose their homes or possibly die out of stubbornness for ignoring the warnings. Some are even struggling to evacuate, especially those with animals at their side.
And finally, what happened to the "video games can wait" thing people have been quoting? Cause for video game fans in North and South Carolina, they have to follow that advice more than ever.
EDIT: In response to your other post, my first comment was a jab. A dark jab, but it's pointing out that even though they delayed a event that was out of anyone's foresight in a landslide disaster, they chose to release the Direct on a event that we DO know a disaster is coming.
