The title of Hell in a Cell doesn't carry the same weight as a Finishing move simply titled "F-U", especially when you go back to understand the exact meaning of that is to imply saying "fuck you" as was the case, from Cena to Lesnar, when he created the move to begin with.
Meanwhile, they changed the title of One Night Stand to "Extreme Rules", because of the original title having a sexual meaning on some levels.
However, Hell in a Cell is neither offensive nor damaging, at least not in the same aspects of the other two name/title changes.
If you look, they went away from having a Pay per view titled Armageddon for a year, in 2001, due to the 9-11 attacks. But a mere year later, went back to the title. I don't forsee that Pay per view getting another name change until possibly 2010, especially with the Mayan's belief.
In the end, I DO NOT believe that they'll be changing the Hell in a Cell title.
