Asus now has the RT-AC66U router listed on there website. http://www.asus.com/Networks/Wireless_Routers/RTAC66U/#overview From what I read around the web the RT-N66U and RT-AC66U share the same firmware. The hardware is the same with the exception of the wireless output chips. Broadcom BCM4360 I have a feeling that Shibby's recent tomato build that uses Asus current 18.104.22.168 drivers will work with this router. The AC66U is listed in a couple web stores but it is shown as back ordered. As soon as I can get one I'll flash it and report back.
