Yeah, I think Fuji makes more money with their FP series because they are the only ones doing it and the Instax arent selling as much. At least they released a new mini cam. Maybe that'll spark some interest.
Instax has to be selling waaaay more than the FP film. You can find Instax film in stores all over China. It is EVERYWHERE. It is almost like the old days in that you can just pop into a store and grab some film on the fly.
Even in the camera malls there are maybe one or two stores with a few boxes of FP film in stock. It's not even close.
