It's not that, it's that it has stayed basically the same for four years now, and the "entry level" of CG has risen. Bryce is a great conceot and you could really see a lot of new features from bryce 4 to bryce 5, but it's been a while and we've seen nothing approaching that level of update. Bryce 5.5 is more like bryce 5.1 with poser support, we want a bryce 6. Bryce 6 doesn't mean including every single wishlit feature, but it does mean solving some key issues such as render times, "advanced" render settings (which are present in most freeware renders now I might add), and some type of plugin architechture to allow for an accessory market and extra functionality. Doesn't Daz want to return on its investment? If so, it needs to sell new software that people like us are willing to buy. And to do that, there needs to be a significant new version of bryce.
