I have strong feelings about this, so don't take this personally.
I hope we won't be seeing those signals. To expect the signal providers (cable and satellite) to quadruple the bandwidth used by locals is totally unreasonable. Satellite providers already have to provide bandwidth for 1200+ SD local channels and are choking on providing HD bandwidth. As I've said elsewhere, there should be East and West feeds of ABC, CBS, Fox, NBC, The CW and MyNetwork morning, daytime, prime time and late night programming. Only for the locals that offer meaningful programming desired by millions should we have to bear the cost of this expansion. What's happening is that in most cases the locals will use services such as the one MGM is offering to fill those extra signals with old programming from their dusty vaults.
