Xbox 360 802.11n wireless adapter.Looks like Microsoft is ready to win back some of the profit it lost when it cut the price of the 360 this year. Gamestop has just added the new 802.11n wireless adapter to its online store for a whopping $99.99. That’s an insane price for a wireless USB adapter, made worse because it’s such a big performance leap for gamers looking to go wireless.

Here’s the copy from Gamestop:

Designed for versatility and ease, the Xbox 360 Wireless Networking Adapter ‘N’ enhances your Xbox 360 experience in the digital home, seamlessly synchronizing with the Xbox 360 system with the newest Wireless N standard. Wireless N offers increased speed, coverage and reliability and can easily stream media-intensive applications such as ‘Games on Demand’, HD movies, videos and music to your Xbox 360 system from Xbox LIVE® or your Media Center PC.

Oh how I long for the day wireless gaming will be reasonable. The adapter will be available November 3rd.
