GamePlan has sucked the last few years as the games are unwatchable in SD. It was rumored that there might be some games in HD last season, but it never came to pass. And I doubt we'll see any games in HD this year as it doesn't even sound like they will have ESPNU in HD until next year. I think D* is tapped out on bandwidth until D13 goes live. Apparently they get enough subscriptions that they don't feel the need to be creative and find the room for HD feeds.
Espn does not even up link all games in HD and you do see a bit of stuff on espn1 HD and espn2 HD that is not in HD.
