Big SE might see the $$$$$. The restriction to travel to Australia and New Zealand would be the perfect excuse to use to deflect any criticism.
Ahem

Tourists are not able to enter Japan. You may be able to enter Japan if you have a valid Japanese residence card and re-entry permit.
And as for restrictions, those are about to be thrown out within four weeks or less. People do come and go from Aust now as it is, so you are wrong. The travel restrictions are due to be lifted completely very shortly..I am also told that the OCE servers have been in discussion long before Fanfest.

I am also told that the hardware may already be in place. So no, OCE servers that have been in planning stages for years wont be handed over to Americans.
