Average print size?

[Tysdagr]

OK, starting off my first post here with a question.

Any guesses to the avg. number of copies of an OST is printed? With big names like Final Fantasy XII it "sold 31,000 copies as of January 2010." Guess my limited edition copy isn't so limited.

But what about the smaller franchises? Persona, Street Fighter, Ace Combat?

The market for VGM is pretty small, so does 5000-8000 sound good for the not as popular stuff? Just curious.
