KEY POINTS
  • Disney movies such as "Toy Story 4", "Frozen 2" and a live-action of "The Lion King" will debut already on the new platform

  • Netflix's shares were down more than 4 percent on Tuesday in extended trading following Disney's announcement

Disney's announcement of a streaming platform in 2019 comes too late and is "probably arrogant," a U.K.-based fund manager told CNBC Wednesday.

The company is pulling out of Netflix to launch its own consumer streaming service in two years' time, starting in the U.S. to then be expanded worldwide. Disney movies such as "Toy Story 4", "Frozen 2" and a live-action of "The Lion King" will debut on the new platform. However, the decision hasn't convinced everyone.
