Not true.
The only issues for the ISPs are upgrading their networks to handle the peak
load requirements. Remember, most of the content people will watch will still
be delivered via IP Multicast. The CDNs will handle the increased server loads,
building out more mirror sites.

You are overstating the problem. Yes VOD will grow, but there are many ways to
mitigate the bandwidth crunch. For example, lets assume that you like CSI. You
pay a small fee for the CSI app, and new episodes are downloaded to every
subscriber during off peak hours using IP multicast. The subscriber then
watches when they want to.
You are also forgetting that networks are getting faster. By the time we
actually get to Internet TV, it is likely that an HD movie may be downloaded to
local cache in a burst that takes only seconds or minutes…
We are already reaching the point where there is little real need for better TV
image quality.

Well at least we can agree that there is still uncertainty. What is certain,
however, is that the congloms will use their market and political power to keep
control of their business as long as possible.
