I've heard initially it was ABC for the majority and ESPN 2 for the east. I don't know anything definitively.
Not real sure how this works out:
Sat., Sept. 4 Connecticut at Michigan 3:30 p.m. ABC and ESPN2
Sat., Sept. 4 Texas at Rice 3:30 p.m. ESPN
Sat., Sept. 4 UCLA at Kansas State 3:30 p.m. ABC
Sat., Sept. 4 Kentucky at Louisville 3:30 p.m. ABC
*edit- Got this off an LSU site.
UCLA at Kansas State 2:30 p.m. ABC / ESPN2 *7 / ESPN-GP *2
*7= Reverse Mirror = Out of market ABC coverage for the Big Ten game will be on ESPN or ESPN2. The other game will be on ABC in its region, on ESPN or ESPN2 in the Big Ten region, and on GamePlan everywhere else..
*2 = Check ESPN's GamePlan's Blackout Schedule or GamePlan's TV Schedule for black out locations.
