I see the SEC Network coming, but probably not till closer to August /Oct. when the football season gets rolling.
I expect it will be set up like the Big Ten network, it's free in the conference areas and a add on for the rest of the country.
Fwiw, I don't see the big deal with the channel ... the B10 Network has been on for what 3 years, the only time I watch it for the most part is the few times that My team is forced (scheduled) to show up on it.
If your a fan of a Major SEC team, your games won't be on the SEC Network but once or twice all year (for football), what it's great for is when your a fan of a team that is NOT covered regularly on the major channels.
I wouldn't expect to see to many Bama, Fla, LSU type games on the network.
I think in the Big 10 each team is required to be on for 2 games a year.
