Cell phone porn in the US specifically is going to mature over the next 5 years however, you must also realize that while the US market is maturing to the same level of cell phone usage / technology in the rest of the world, the rest of the world is always going to be 5 years ahead of the game.
Therefore, it goes without saying that the serious $ to be made from cell phone porn will be from those companies who embrace the technology now and will be making big bucks in roughly 2010.
That being said, five years in an unstable market can really have a negative impact on any of the companies who are starting to look at cell phones as a viable billing and content delivery medium.
