The new generation is already out. We run ethernet to the living room through the power line, used to have the old 200Mbit/s units but in January I replaced them with Netgear's AV500 units. The specs say 500Mbit/s but that's a) marketing and b) link-rate rate. But one should expect 2-3x increase in performance.

I'm currently getting 200M down/100M up link rates. With the 200M units it was kind-of slow for e.g. NAS access, now it's finally ok.

There is also 4-port gigabit model available (XAV5004).
