Productivity is the key here. realistic ecosystems on one hand, realsitic models and studio professional animation & modeling tools on the other hand. Make them talk to each other, and save hours of closing/reopening/compositing... Definitely for the pros. I agree Vue has more of a hobbyist follow up, and e-on wants this to change, hence Infinte and xFusion. And I think that if it works fine enough, it will sell. You can't beat ecosystems right now. But Terragen 2 is coming soon... so e-on had to find something to stay ahead. something with an x!
