The problem with native content has been repaired; I can't speak to the Bryce issue because I don't use it. I'm not sure why there's an issue of free vs. upgrade here. Why not have both? You can easily use D|S with most Poser content (except for the dynamic stuff). I've found it much easier to do production quality renders with D|S than P5. However, someone who's used Poser exclusively might not find that to be the case. If you've got the spare cash, go for P6. If not, give D|S a try. No reason to wait.
