Upgraded DOCSIS 3.0 Comcast markets see the company's $42.95 "Performance" 6Mbps/1Mbps tier become 12Mbps/2Mbps, while their $52.95 "Performance Plus" 8Mbps/2Mbps tier becomes 16Mbps/2Mbps. Upgraded markets also see two new tiers: $62.95 "Ultra" 22Mbps/5Mbps and $139.95 "Extreme 50" 50Mbps/10Mbps.

While many cable carriers have taken a "wait and see" approach to DOCSIS 3.0, Comcast has been very aggressive with the upgrades. According to the carrier, 65% of their customers will be upgraded to the faster speeds by the end of the year, and 100% of their customers will be upgraded to the speedier technology by the end of 2010.

Interesting. I already have 20 Mbps download and 2 Mbps upload with Comcast in the "Performance plus" plan but with a phone bundle I pay only $42/mo. I think because my neighborhood is only 35% built out I achieve higher rates and with the housing meltdown, I don't expect BW competition for a few years.
