The thing is what exactly is so pro about the features that they have included in the pro version? Blurry reflections are avaliable in Bryce (nothing really pro about this), Transposer is only useful for people with Poser (again not many 3D pros are poser users) , Cadstyle is just a set of import filters. I think that the Inclusion of Amapi Designer is a great idea and my hat goes off to Eovia for this. The network rendering is definately a pro feature. With Amapi the split between pro and designer felt natural because not everyone would want nurbs or be willing to pay for them. The pro and standard versions of Carrara feel very artificial. It is almost like they did not have enough reasons to justify the split so they threw in some plugins to justify it. The core application does not seem to have changed enough to warrant an upgrade.
