How's this for a ball-buster scenario?
D* wanted to release on the 19th. A problem with the billing computer fouled things up, as well as some sporadic, intermittent technical problems with the sat itself. The billing problem was the easy fix, and the programmers have already applied the patches to fix the problem. The sporadic, intermittent problem with the sat was probably believed to be able to be ironed out by Saturday, so the Sunday release rumors left the corp. They even put up a channel to announce that Sunday was the day! But today, they've discovered that the sporadic, intermittent problem is not so easy to track down. So they pushed back, all the way to edge of the end of September, with still no fix in sight (and they pull the release announcement plans on 570).
This is practically their last play. Once next week rolls around and the problem still persists, even with Boeing and D* working around the clock to fix it, they push back one more time...to Saturday, September 29th at 6:00 AM. That will give them 48 hours to finally fix it.
When that fails, the wheels fall off. You guys hit the roof. Providers like Big 10 Net become unhinged because they're losing revenue at the height of college football season...and D* has egg all over their face.
October 1st, 2007 will be the first real customer service communication you'll have from D* about D-10 and what's going wrong. They'll assure you that more HD channels are coming and they're working hard to release as many as they can as soon as they can.
I predict you'll get your channels on October 20th, 2007.
