I was talking to someone who works in engineering at a competitor to Dish, and they "ceased worrying about Dish as a competitor months ago".
He said AMC 14 would help them in the short term with local markets in the eastern quarter of the US. But that's it.
He said he would be surprised if there were any national HD from this before June or July, because they don't have uplink capacity in the right places.
He also said he heard that E11 would be delayed by several more months for technical reasons (Sunspots?), though he did not know why.
What this competitor IS worried about is the new Echostar forming a partnership with Dish and Directv to provide ALL LOCALS for all subscribers of both services. In the long term that would free up LOTS of space as well as digital locals for all markets in the US.
So maybe AMC 14 is not the panacea we all think it is.
Can't see uplink sites limiting Dish providing national HD, possibly HD locals. The latest schedule has E-11 going up in June of this year. I really question the accuracy of your source.
