Mike, if they put HDTV at 105, the customers who have a SD today that is aimed at 110/119/121, will not be able to get HDTV.
I think the locals that are there today stay at 105 and 121, and new HD gets added to 61.6 and 148 and picked up with a 2nd dish.
The lesser locals on the wing sats go to 110/119 after E* X goes up.
New local markets are added to 105 and new internationals are added to 121.
Not sure if today's HD are migrated to the wing sats to join the new HD, though. Seems like an easy deal to give current HD folks who do not have the 2nd dish installed a 2nd dish. There can't be more than 1 or 2 hundred thousand of those out there. Dish would have to wait for the DP 44 before moving current HD (HBO HD, etc.) back to the wing sats.
