If all TV content starts being delivered over the internet, you can bet your life that the cost will increase to deliver internet access. Cable companies subsidize the infrastructure costs with their cable TV revenues. Lose that and they will have to raise the price of internet access to cover the now unsubsidized costs. Will the "TV over internet only" price be less than the existing combo price of internet/cable TV - Yes. But it will never be as low as the currently subsidized price of internet access.
