Agreed that Fox ED is a big letdown when compared to CBS HD. With the latter you can see tiny details of the players even on the longshots. The Fox picture only looks good on closeups and blocky on the longshots. Luckily this must have also been apparent to the execs at Fox

I was very lucky to be able to watch most of the Cowboy games in HD/ED this year. If they had not "surged" to a better record it would have been a different story I'm sure, but the Dallas market combined with a competitive team (TBD in the future I know) caused Dallas to get boosted in terms of both broadcast team and ED priority.
I haven't heard any more about it, but there was some talk about Monday Night Football being able to select their matchups on a week-by-week basis in the future, leading to more interesting games late in the season. What this, plus the allocation of HD slots for the Sunday games, means is that the better games will have better quality.
Of course, if your team sucks you will probably be watching them in SD
