Why the assumption that cord cutter growth will stagnate? As more people do it, the "cordless" options will get better, and even more people will switch. I predict by 2020 or so, fully half of the current TV owners will have left the normal TV providers...Here's what I see...
Even if the rate of cord-cutting increases 100% next year (but it won't) and remains there (2 million cord-cutters a year), it will be at least 12 years until the TV subscribers dip down to 71 million from the top providers in the US alone (94.5 million is current number). That's around or more than the total number of Xbox 360 consoles sold to date world-wide over it's entire lifespan. It's still a major feature that could be used by more people than they have ever sold to before.
So ToTTenTranz, long-term it doesn't amount to anything.
