I think Charlie is a big SEC/ACC fan, and he will do all he can to roll out the ESPNU HD as quickly as possible. (Almost said "soon." : )
If he is an SEC fan, he would have rolled out ESPNU-HD at the end of August when College Football season started. I've suffered through many an SEC game this year on ESPNU in SD, when I know they are broadcasting in HD.
Unfortunately, I've learned a valuable lesson with E*. I don't look for them to add HD anymore...I'm just happy when they do. Otherwise I'll be let down a good bit.
