Putting Verizon FiOS’ 50Mbps Up / 30Mbps Down to shame is Comcast’s announcement to implement it’s new DOCSIS 3.0 infrustructure in 2008, with 20% system-wide availability by the end of 2008.

It will theoreticly max out at 160Mbps down speed, which is a whopping 20MB/s. That would enable a computer that has a good enough performance level to handle lots of connections from a P2P client to download a full length movie in just a few minutes. It will also mean an Up speed of about 120Mbps or 15MB/s. (If you’re confused about the units, Mbps is Megabits per second,while MBps is megabytes per second. one MB is larger then one M. Bits are commonly used in internet talk because companies like it since it looks like you’re getting much more for what you pay for. Google’s built in unit converter will translate them if you need it. Your query would look like this: 160Mbps to MB (which would be 20.))

What’s surprising however is the sudden announcement to release this new infrastructure and make it so widely available by the end of ‘08. At that rate we would expect full integration by 2010.
