Did find this today:
http://www.gamestop.com/ps-vita/consoles/playstation-vita-wi-fi-assassins-creed-iii-liberation-bundle/102637
Gamestop has the bundle priced at $250 for pre-order. Whether that is true or not is anyone's guess, but that's equal to a savings of $60, assuming the game at $40 and memory at $20.
Assuming any of that is true hints that the vita will be getting a price drop (prob to $200) around the same time. Or they're going to sell both at the same price... which seems kinda dumb.
