Just as far as this goes: "Yes, he will continue to earn money from it. But I imagine most of his true fan base will have already purchased it by now, so how many people are there really left to reach?" Fan bases are always growing/shrinking. That statement is the equivalent of saying that Michael Jackson's "Bad" album probably saturated his fan base in 1987, and he probably didn't make much money off of it in the 24 years since. I wouldn't underestimate the long tail.
