There should not need to be a spare though. EB has placed N orders with Hasbro; EB will still receive N orders when production is done. The closure of a single store should never have any bearing on N (and neither should someone voluntarily cancelling their order at this point) - the only change should be whether it is picked up from a different location or posted, and EB should be reaching out to arrange that instead of cancelling.
I'd be contacting EB about this right away. And probably your state's consumer affairs body too.
