I think the holiness movement as described is dead. However, there will always be folks trying to add to the word of God.
We see a lot of the same confusion of the holiness movement in the charismatic and pentecostal movements. Folks are always trying to find a newer and easier way to live for God. We will constantly see these fads and trends happen as long as people don't have a strong understanding and hunger for the word of God.
There is a book by Dr. Harry Ironside,
Holiness: The False and the True that describes his conversion from the holiness movement and the confusion that he suffered because of the teachings of the movement.
Here is a link to some of his writings.
