Well, while possible it's highly unlikely, it would be akin to Apple deciding to sell Itunes for $50 or even $500 after all they dominate that market.

Doing that would only serve to threaten the established business model and not really make a great deal of commercial sense.

Also there is no reason to see a large hike in general product prices either, it would just open the door for competition.

Daz3D still competes with the other marketplaces that sell products for use with Daz Studio.
