Microsoft's releasing a Wireless N Networking Adapter for the Xbox 360? Get out of town! ... Oh, wait, we've seen it. Constantly. For the last two months. Ah well, let's just all be happy to see it finally appear on US store shelves, putting an end to this sordid saga and supporting 802.11a/b/g/n for a copper Lincoln under $100. As Joystiq reports, the old 802.11b/g model is slowly being shown the curb, with the current stock being discounted at $80 while supplies last.
