I want to be wrong about that. Seriously. Send me a link to one. I want to be wrong. (And by residential, I mean a CPE/router/firewall that costs less than $150US.)

Any device with a docsis 3.0 cable modem embedded in it (Scientific atlanta/cisco DRG2800 for example)
probably more now that CES is going on right now.
Thanks for the links. I'll have to investigate the airport extreme's IPv6 support. At a $180 it's at the extreme price end for resi, but it's closer. Do you know of a north american vendor for the ampg300nh? I don't know Japanese, so I could not glean it from the page. Not that familiar with the cable modems as we are a dsl CLEC, but it's good to see resi cpes with IPv6. John
