PAX West says they are planning to go on. Pretty sure this is just legal/contractual obligations. If they cancel of their own volition, then their insurance won’t pay out, they’ll be on the hook to pay the convention center, etc. If they’re forced to cancel, then they get out of all their contracts. Since it’s too soon, they’re required to say they plan to go on, for now. I give it a < 50% chance of happening.
If you buy tickets, make sure everything is fully refundable. If it happens, will I go? Maybe.
