I called them too, and they said they are getting more in stock. Supposedly she told me if they absolutely did not have anymore then the order would've been canceled.
Also, she said that the order will get canceled in a month if the status of the backorder doesn't change, and you could extend...
Already own a copy of Bioshock 2 for the PS3, great game and I loved it, but had to bite on this deal anyways. Thanks OP. Status atm says backordered though :/
