All reviews are done in real time. Challenging team picks up to three angles to look at. Maximum of two replays per angle (or if less than three angles picked, there can be more than two reviews but a maximum of six total). If the officials can't see a problem at game speed, then it probably wasn't enough to impact play to begin with. Delay of game to the challenging team stays as it's a good deterrent now let alone at game speed reviews.
Studio talking heads are each fitted with a shock collar. If, during intermission, they start whining about how the officials missed the call by an inch or less, the officials are given the option of making the guys in the studio dance for our amusement. Think of the ratings. Think of the side bets on who will make who dance. Win/win for everyone (ok, maybe not the talking heads but then they shouldn't be trying to stir crap up to start with...)
