The latest (cough, gasp, weeze!) prices for all versions of Vue tells me there isnt much competition around at the moment in the field of 3d environment modeling.
Bryce's last update was lets face it a joke and while many apps have some lanscaping cheats and work arounds, well they're just that cheats and work arounds.
I'm not gonna complain about the pricing for Vue, we know it $uck$ but that looks to be a symptom of no competion.
I fear that this will continoue until someone wakes up to the fact that there is a cornered and overpriced market that is ripe for a competiter.
