Any idea when a DOCSIS 3.0 emta will be offered by Comcast? I currently have the 6120 but am considering moving to CDV and don't want to lose my higher speeds.
There are 2 options. You will either have a Dual modem set up where your 6120 will do the net and the CDV modem will do phone.
Or since Docsis 3 has really gotten going now, you'll get an ARRIS 702G which would do both net and phone on 1 device.
From screenshots I've seen of the 702G doing internet, speeds are comparable if not equal to the 6120.
Hope that helps.
