I think, when looking at some comments on the official e-on software that the most important change in this version has been totally overlooked.
The implementation of a real gamma linear workflow (and a well implemented one at that, very similar to the one used by 3ds max for mental ray), is something EXTREMELY important. 
Not only, it will make the life of professionals a lot easier (working with xStream, outputting images in float for further compositing... ), but it will have a very big impact on hobbyists (like me).
Most people will start to really realize this (if they use it properly) the first time they will try to make, an interior or semi-interior render. 
When using a quadratic light, they will also start to behave as they do in the real world, not this very harsh light that totally disappear within a few meters unless you crank it up like crazy. Instead, a light that slowly fade away, like what you are used to in your everyday life.
I've seen wonderful images by extremely talented artists in the gallery that looked "wrong" (honestly, mine didn't look better and even worst since I was far to be as talented as some of this artists). Bright zone, harshly turning into dark, extreme color saturation near the lights. The introduction of a real gamma workflow (once properly understood) mark the end of this era.
For those who are curious to know what I am actually talking about, a modo user posted a very well done "beginner introduction to linear workflow" on you tube. It is meant for modo, but all the information are relevant for the new functionalities in vue.

NB: I don't work for e-on, I'm not a beta tester and I do pay for both, my vue and my subscription. I only post this because I do think it's REALLY what finalize vue's transition to the professional world
