Actually there is a good deal of uncertainty about the revenue potential of the ACC Network. Much smaller fan base than the B1G or SEC, only two flagship state schools, four colleges in one state, six small private schools and Notre Dame without football.

The ACC is defiantly behind the Big Ten and SEC right now. However, they are already ahead of the Pac 12 in money distribution to member schools, and they'll surly pass the Big 12 once they start cashing in on their ESPN conference network money.
I also think there is a very good chance that Texas chooses the ACC in the next round of realignment. Texas will choose between the Big Ten, Pac 12, and ACC.
Texas could go to the Big Ten if that's what Oklahoma chooses to do, but I don't think Texas wants to be in a northern league. They really won't want to appear that they're following OU who broke up their conference. Also, the ESPN owned Longhorn Network will collide with the 50% Fox owned Big Ten Network.
Texas has had so many chances to go to the Pac 12, but never ends up going. They could take three Big 12 members with them, but would still have to play half of their games two time zones away. This wouldn't be so bad for football, but when the basketball team has a game in Seattle on a Wednesday night and the players are expected to be back in class on Thursday morning, you have a problem. And again, what do you do with the Longhorn Network?
Texas could join Notre Dame in the ACC as the 15th and 16th members, perhaps even playing ND on Thanksgiving Night like Texas likes to do, creating an annual ratings extravaganza type game. Texas has consulted with Notre Dame regarding conference realignment in the past. This isn't a surprise as they both look down on the rest of the NCAA schools. Don't be surprised if Texas and Notre Dame work together again.
ESPN would also love this move. They could roll over the Longhorn Network into the ACC Network, thus eliminating the dead wait of the Longhorn Network and strengthening the new ACC Network.
There are lots of reasons why Texas would be a good fit in the ACC, both athletically and academically. If they choose the ACC with Notre Dame, the ACC could quickly get on equal footing with both the Big Ten and the SEC.
