Disney is coming out with their own subscription service (or already has?) called Disney+. They want to use the characters from Marvel, Star Wars etc in their own original series, so you will soon see a lot of new shows using these characters. I don't think they are specifically continuing on with Daredevil from where it left off for example, but there could be new shows using the same actors. They made an agreement with NetFlix so they can keep the current finished episodes/series, but not make any more. That's why they were 'cancelled', it wasn't to do with ratings or quality, even for the lesser ones like Iron Fist or Luke Cage etc. If it wasn't for Disney wanting the bigger piece of the pie (as usual), I think every Marvel show on NetFlix would have been renewed.
