At this point if you want it new, I'd just bite the bullet and get it from Newegg while you can. Otherwise there probably will be chances to get it used for $10 or less at a Hastings sell or something similar pretty soon, if it is in stock, but its always hit or miss with the condition you will get it in from Hastings. Thats why I only get previously viewed and used games from them during a good promotion, so its a better gamble.
There probably wasn't much of an inventory to begin with, I don't think they had a huge printing of this one, since its more of a fan service type game.
