If this is a strictly "hardware" discussion, v6 "works" on a variety of models, albeit not with stock firmware. To wit : http://www.dd-wrt.com/wiki/index.php/IPv6 This suggests that Cisco (et.al.) can release an "official" firmware image to support v6 on existing devices whenever they're sufficiently motivated to do so. I'd wager the only reason it hasn't been made GA is to limit the number of "pass-the-buck" support calls that start at $isp and get bounced back saying "we don't support that yet, call whoever makes your router".
