Ah okay. Thank you for answering that question. That does kind of suck. There will be no point of picking something like that up as pre-owned from GameStop or elsewhere then.
Was wondering the same thing, but I checked out this unboxing video and it seems that everything is on 1 disc for the PS3 version and you just download Liberation from the disk to your HD. So no voucher as far as I can tell. 360 definitely is a voucher unfortunately.
