Comcast just rolled out Upstream bonding in my area this week. Had downstream bonding for a couple years. It is taking years to roll out Docsis 3. Imagine how long before they roll out any updates to it. And Comcast is one of the more aggressive providers in rolling out D3.
supposedly it's just patch for the docsis 3 gear that supported upstream bonding already.
To bad they won't start working at upgrading current plants to be 2200 mhz capable that would be an awesome thing. -- "It's always funny until someone gets hurt......and then it's absolutely friggin' hysterical!"
