Will Camping's followers say what SDAs and JWs so often say, "What? We never said the world was ending!"?

I know that that sounds incredible but both Seventh Day Adventists and Jehovah's Witnesses backtracked after their prophecies failed and will claim with a straight face that they never EVER made such predictions. (Indeed, newer members of those organizations have no memory of those predictions so it is very easy for them to deny them. Nobody is going to tell them the truth and they aren't likely to read any history books on the subject.) So will Harold Camping's followers do likewise?
