GameStop has recently put up a listing for the Xbox 360 Wireless N network adapter that we’ve been hearing about for some time now that lets us know of both a release date and price.

Of course, GameStop has been known to put up phoney release dates as a place holder until the manufacturer actually speaks of one but they currently have the adapter listed as releasing on October 3rd at $99.99.

A steep price but if you’re looking to ramp up your wireless connection this is your answer.

Microsoft’s new wireless adapter for the Xbox360, one that supports the new N standard (offering greater speed and range), has revealed that it’ll cost $100. The older adapter will not be discontinued, rather, it’ll be lowered to $80.

These prices are still far too high, considering that the PS3 and the Wii have WiFi built in. The new adapter, with its high price, will be arriving in stores next month, just in time for the next Xbox 360 dashboard update.
