I just received an email from comcast, that with the launch of Docsis 3.0, users can experience higher speed connections.
For example what used to be 6 Mbps download / 1 Mbps upload is now pushed to 12 Mbps download / 2 Mbps upload. The speed is doubled in both directions. Come on Microsoft, I dare you to send me bigger downloads!!
Comcast is also offering two new speed tiers:
Ultra 22 Mbps download/5 Mbps upload and
Extreme 50 Mbps download/10Mbps upload
