USC ran a ton of 3-4 last year. I watched their last 3 games vs. Cal, UCLA, and Michigan and I don't recall them running a 4-3. Cushing it just a stand up DE basically...same thing we will prolly be doing w/ Campbell.
So, yes, Nebraska will see plenty of it before we go to Lincoln. Mizzou will see it in their sleep. OU went 3-4 all game long on them last year in Columbia and that worked so well me thinks they might try it again in Norman.
