I've recieved an email as well, If it's the same news letter I recieved then it's basically just saying that Vue 5 is about to be released, it says:

Dear customer, dear friend,

E-on software is happy and proud to introduce you to the latest release of your favorite 3D application ;-)

It's now been over 3 years that Vue 4 was released. Three years of hard work to turn this new generation of Vue into the ultimate natural 3D environment tool! Last year saw the release of the professional line of Vue products, but this year, with Vue 5, we're introducing a whole new generation. Vue 5 Esprit will ship at the end of the month, and Vue 5 Professional before the end of the year.

You can start pre-ordering Vue 5 Esprit right away!

The list of new features in this release is bewildering; see for yourself:

• Global Illumination and EasyGI

• Global Radiosity

• HDRI and Image Based Lighting

• Procedural Terrains

• Advanced Atmospheric Engine

• Compatible with Vue Professional Plant Technology

• New Material and Function Editors, Parametric Mapping

• Metablobs Organic Modeling

• 3D Text Editor
