I've been thinking about this, and want to see what some folks think.
I think the move on spotbeams for 61.5 is really related to the BTN.  They made some statement about how they will go to a regional in the spring.  Now, move these from the national list to the spotbeams, along with adding (hopefully) several local markets, you can throw in some new nationals and bing, you can keep doing stuff through the year till they get the satellites up.
I also think while they have lots of extra space, they really don't.  With the delays in launches, if one fails, they need to have the ability to move channels around to keep the programming they have in space.  I think they are really out, and all they can do is shuffle the deck chairs until the new birds are up.
Thoughts?
