Whatever it is, it won't be enough.
Blue Dragon and Lost Odyssey were near masterpieces, and greatly under-performed compared to the quality put in.
However, if pre-orders are ~65k with 1 week left of pre-orders to go, I would imagine first week will be around 110-120k....Certainly low given that Blue Dragon did ~83k on an almost non-existent user base.
Back from the dead, I'm afraid.
