I'm looking forward to using Poser 5's Judy with the new P5 Face Room, but her joints don't look to be greatly improved, especially looking at frames in the animation - although it could be that the renders we've seen so far don't show them to best advantage. I take it V3 has a higher resolution head, but it seems better shoulders, elbows, hips and knees would be a big selling point too, especially as folks' computers continue to get more powerful. I haven't invested a lot in V2 clothes (waiting to see P5's fabric capabilities), but a V2 body alternate would probably be necessary.
