Forum:Secret Armory of Knoxx download without XBox connection to web

My Xbox is not connected to the web, so I cannot download Secret Armory directly to it. Does anyone know when this add-on will be coming out on DVD like the earlier two add-ons just did, or does anyone know if it is possible to download the add-on to the computer, burn it to a DVD and then install it in the XBox? I appreciate any advice and assistance fellow members can provide.
