The folks who previously submitted NES emulators, and were rejected, must be more than a little annoyed right now. At $6.99 this developer is going to be making some pretty good money especially with the wave of free PR. It would be interesting to see if this app has some extra layer(s) of sand-boxing or other security that made Apple willing to accept it. From a PR standpoint it would be quite clever for Apple to just start accepting a lot of these taboo apps and they'll look like the great hero of the people acknowledging their mistakes and moving forward. Crazier things have happened.
