Then again, sooner or later they're going to have to put in some high end features, because someone else will.
As technology improves, people expect the software to improve with it. In spite of its recent leaps and bounds,  Poser is still lagging way behind. True, relative to itself, 5 years ago, it's a huge improvement, but meanwhile the rest of the 3D world has advanced far, far more.

DAZ Studio is becoming a contender. They're incorporating high end features now. Sooner or later Poser will have other competition too, and it won't be good if they suddenly find themselves replaced by other apps by other developer who were willing to take the leap.

Having said that, as long as they keep the price low, they can count on the budget hobbyist market, probably, and probably continue to get away with being at the bottom of the 3D heap.

But "pros" or people wanting pro features may not keep spending 500 bucks on it once other apps offer more high end features.
