I don’t know if Autodesk is going to come in with the fee hammer. Their management seems to want to bridge the maker-corporate client divide. I read that the CEO is really into sculpture and carpentry and wants to support hobbiests. It kinda fits with the Innovator’s Dilemma too. 3D is bound to become cheaper and cheaper so the 3D software companies need to get ahead of this by adopting a low cost strategy.
Lastly, I’m pretty sure students will be the first to adopt Fusion. In five years, when there are 100,000 Fusion experts on the market with no SW or Rhino experience, companies will start buying a couple of seats.
