Looks great, if its base of their Bigfoot Killer series, should be awesome.
But, my DGL-4500 is running like a champ still, not sure if its worth blowing money just for the sake "mine is bigger than yours"
Would not get much use from the wireless improvements, since all my important stuff is wired now (DLNA clients, ps3, & xbox360).
But their QOS from Bigfoot technology is top notch, especially for lag and ping times.
