The Wireless N Network Adaptor for Xbox 360 will be available from November 26, Microsoft announced today.
The new adaptor takes advantage of the 802.11n protocol to deliver, according to Microsoft, up to twice the range and seven times the speed of the older model adaptor. Oh, and as you can see, it's got two antennas!
It will retail for $149.95 RRP, the same price as the older model. No word on whether both adaptors will be sold side-by-side or if the old one will be phased out.
UPDATE: Microsoft has confirmed the older model adaptor will not be discontinued. They did not comment when asked if the price would stay at $149.95.
