They said they would offer up to 80 games a week in HD. These are just games, not the feeds. I do not know how many dual feeds will be offered.
That's true but if they already have both feeds uplinked for RSNs why wouldn't they give EI customers access to both. I think they will. Now if they don't carry one RSN involved or one RSN doesn't have HD available on a given night there will probably only be one feed.
