The "new" presentation was:
- Gus Johnson
- Drew Brees' Pep Rally
- Locker Room scenes + Random Fan Cameos
- More Sideline chatter
I use the word "new" facetiously of course, because none of the additions are really new, just expanded alterations of what we already had. Pretty sure they didn't do anything to the half-time show (since none of the E3 invitees have commented about it).
