Sorry if this has been posted, but apparently Texas and ND have reached a 4-game deal:
"The Longhorns are scheduled to play in South Bend on Sept. 5, 2015. The Fighting Irish are slated to play in Austin on Sept. 3, 2016, and again on Aug. 31, 2019.
The Longhorns return to South Bend on Sept. 12, 2020."
I was a little surprised to see ND going after more high-profile games, you know, since they're trash and all.
