Obama wins NC and IN (any margin, whether it's 10% or 10 votes in IN): Supers endorse en masse this week and force Hillary out. This is really the only possible scenario that I could consider a game changer.

Obama wins NC and Hillary wins IN (by any margin): Not much changes. Maybe some supers will endorse and she'll concede, but I think we'll go on to the next primary.

Hillary wins NC and IN: Definitely the least likely outcome. Even then, I don't think it will change much. She'll claim momentum, much like she did after PA. She'll say it's a game changer, and she's more electable, and Obama can't win big states, and Obama can't seal the deal and continue spinning it, but the math will still be against her.

Obama wins IN and Hillary wins NC: Hell freezes over. Satan, in search of a warmer place, comes to earth to rule the world. All of the world's governments are disbanded due to Satan being in charge, thus, making the Democratic primary irrelevant and unnecessary. Hillary and McCain, since they're most like the prince of darkness, fight to the death to determine who will be Satan's vice ruler of the world. Hillary has the advantage in the duel due to her uncanny ability to evade sniper fire.
