Why should these features be restricted. A Plant edito, for example, is a natural evolution of the already established SOlidGrowth. Wind effects for still or animation rendering is another natural evolution for the render engine in Vue. The point is, why should these features by restricted to professionals? What constitues a 'professional' product, besides the inflated price tag. Vue 4 is an absurdly powerful program, if E-On want to expand this to professional applications, such as Lighwave and 3DS MAX etc, produce a plug-in that links them. I think this is a really rough deal, either upgrade and be hooked into more expensive product or don't and be damned. It's a blow for us loyal Vue customers.
