It does make sense but don't forget that the Dish webpage that lists the HD packages also still lists FSC HD under AT120Plus, with the disclaimer that it's not available on AT200.
It seems strange to me though that the HD version could be kept back for AT250 subscribers but not those who subscribe to the multi sports package.
Good point. Why do they discriminate against AT200? Also, FSC doesn't seem to show up under channels available for any package other than AT250 for the Standard Definition version. So is it a Multi-Sport pack only channel? And whether or not you get it in HD is dependent on what regular package you subscribe to? That all seems too complicated.
