I hope/assume more are being printedIt's a FF game. It's crazy popular at the moment. It's going to get a whole bunch of expansions. So there is no doubt that more print runs will follow, no worries!
You just might have to wait a bit if you want to pay normal price.
not sure where to go to find out when they might be availableThe FF site, this very forum, I'm sure someone will let the community know.
Or you could do what I do, ask your FLGS to hold one aside for you when they get a new shipment in. (And they might also have some information from their distributor on a specific date.)
