Uri,
DOCSIS 2 and 3 do not change the frequency plans in any way. DOCSIS 2.0 adds ATDMA and SCDMA, as well as enhanced modulation rates (8QAM, 32QAM etc...) but the list of available frequencies remain the same.
DOCSIS 3.0 will allow channel-bonding, but they are going to be the same channels you've always had.

Let me know if you have more questions.
