Why the heck are you calling this Vue 4 Pro? This should be called Vue 4.5 Pro. :)

Sounds good but how long will the introductory period last where we can buy the sidegrade? Need a few months to save up for it.

Curious about this
"complete scenes can be exported to high end 3D applications, including 3DS Max, Cinema 4D, LightWave, Maya, Softimage XSI and others;"
Maybe somebody can answer this, but don't those programs render quite faster than Vue? I remember a long time ago somebody (was it Audity?) who rendered two similar figures, one in Vue and one in C4D. The speed in C4D of the render was like 500% faster. I would think that exporting may be the way to go for render speed if that is the case.
