People have been predicting the end of Cable TV for DECADES now and they're still going strong. The large number you see mentioned is not the real number as a significant portion of those have switched from Cable to Telephone TV or from Cable to Satellite providers. That is the sensational but significantly misleading number they always use to get page visits.
- There were 366,000 total net losses across all TV/broadband subs in Q2, according to SNL Kagan.
- The rate of losses is increasing. In Q2 2012, only 325,000 subs were lost
- But telco companies — internet providers who also supply cable TV, in other words — gained 400,000.
- 911,000 U.S. homes have cut the cord in the past year, according to MoffettNathanson.
- top cable MSOs had 50.5 million video subs, ahead of satellite’s 34 million, and the top telcos’ 10.03 million
I think it's still a good move, considering the real stats behind what you posted. What they have switched to is typically some streaming media service such as Netflix/Hulu/Amazon/Etcs or simply using free Over The Air. In that regards Microsoft already has integration with those streaming services covered. For coverage of those switching to over-the-air or satellite subscribers as long as that piece of equipment provides HDMI signal, the Xbox One has the integration covered. They're poised to support all 94.53 million subscribers from the top providers.
Still it's up to the reader to be misinformed from being sensationalized or to be educated.
