Hulu has kept away from a lot of prestige television. It will continue existing series and make new series based on established creators, but it doesn't seem to go for the high spectacle that other streamers do. It also has long term deals to stream TV shows.
I think Comcast is looking to sell its stake as long as it is a minority shareholder to Disney. However, it may want to keep Hulu around to ensure that Hulu's content doesn't get swallowed up by Disney+.
Maybe I'm wrong, but it looks like they could make a lot of their shows for cheap. The writing could be prestige level, but they may be able to control costs better.
