In line with what BShy is saying, I think we're going to start seeing some consolidation in the stream wars. At any price point, people want at least some exclusive offerings, since that's the only way to offer any distinction in the market, so anyone without exclusive content will likely fall first.
TV markets usually have one or two providers and then a satellite option. I think the cable replacement will fall in line with that. There really doesn't need to be more than just 2-3 players on that front and we have Sling, Hulu Live, and YouTube TV. Two of those have enough backing to survive competition, so Sling may have to become a price leader.
Hulu has the advantage of Disney bundles, and I guess YouTube has exclusive content. If everyone else shies away from live cable, they can still exist as supplements/add-ons. Kinda like how premium cable is now.
