Reports that Apple TV will have a lineup of networks in an over the top service this fall.

On-demand, if included, would be a big plus. The cord-cutting generation is used to watching on demand, via DVR or Netflix, and traditional "live TV" doesn't appeal so much. That was one of my problems with the Sling service.
Note that NBC is refusing to participate in any over-the-top services, because it is owned by Comcast which obviously wants to protect its cable TV business.

If FOX is included and brings along FOX Sports, that would solve my F1 "problem". FOX Sports wasn't on the Sling service, because FOX is fighting with Dish over services that allow FOX programming to be viewed on screens other than TVs.
