Vue8? Well, Vue7 was out at the end of 2008 if I remember right, so that would make a year develepment cycle, pretty much like any other major software development cycle these days. 7.5 being a .5 release and not a full point release. Is it going too fast? Maybe, but the new terrain features look very interesting. And since e-on introduced maintenance plans with free upgrades for Vue8, they need to show their licencees that byuing a maintenace plan is a good deal.
