It's always seemed to me that those who complain the most about Poser5 and the announced Poser6 are those who use Poser4/ProPack with other tools such as Carrara or Bryce. If you use Poser to setup figures and animations, then the addition of Firefly probably wouldn't impress you to much. Figure in that most of the memory leak bugs were caused by Firefly and that initially users didn't understand things like shading rate and bucket size and you suddenly had people complaining that the new version (P5) produced inferior renders that took longer to make. Hopefully Poser6 will have benefits aside from improved rendering and new content, or these people are likely to start complaining all over again.
