I believe if you have P5 installed, then Vue will import a P6 file using only the features supported under P5. Vue is using P5 as its interface to open the file. It doesn't know how to talk directly to P6 yet. Vue will release a patch for Vue 5 to let you open P6 files directly but no timetable has been announced. Since P6 doesn't appear to have made drastic changes to the structure of a Poser file, I'm hopeful it will be quick.
