Microsoft is keeping the details of its Xbox 360 Wireless N Networking Adapter firmly under wraps, and though we know it exists, there hasn't been any clear indication of pricing or availability... until now.
Said adapter has made an appearance at UK supermarket chain, ASDA. It appears to be the work of an overzealous ASDA employee, but seeing as stock is reaching stores, we'd expect to see the 802.11n adapter widely available in the very near future.
ASDA has the adapter priced at £49, making it comfortably cheaper than the current 802.11b/g offering - priced by Microsoft at £59.99.
Whether or not Microsoft will continue to offer both adapters side-by-side remains unknown, but it'll need to snip the price of the older 802.11b/g offering if it's to make any sense.
