So far it is not known what a separate sports app for the Prime subscription would mean. However, it is conceivable that Amazon might charge an extra fee for the use of all sports content. The fact is that the broadcasting rights for many sports have increased significantly in the past.
It is not yet clear whether Amazon will really complete the idea with the separate sports app. It should also be decisive whether there is a corresponding interest on the part of the users. Accordingly, there is no release date yet.
