I work for Gamestop and this price is placeholder only.
We also had the 3DS and Kinect listed for $999 when you could pre-order it before a official price was announced. The reason is simple. It is company policy that whenever a product is listed for a specific price we have to sell the item for the price on it rather than what acutal price may be. Thus if we listed that we believed the NGP would sell for $300 and let people start pre-ordering it ,but Sony then announced that the NGP was launching for $400, we would still have to sell the NGP for only $300 to those who pre-ordered instead of full price to avoid false advertising. By placing an incredibly high price point on estimated price it guarantees we don't under shoot and in fact is very common in all companies not just Gamestop.
Simple business practices folks, that is all.
