I was hoping for a Poser 11 upgrade path as well. Nothing. Its still cheaper to buy upgrade to 12, then 13, but that just sounds like crazy way to do it. I can understand they might feel money lost by allowing upgrade path for older versions, but it will be more money lost. E=on did the same with Vue, and I left. Yeah , 1 guy, but how many more? At least Poser isn't subscription. 

Was seriously hoping to bail out of the DS trap and get back to my roots, Poser, but I'm not seeing that happen. To much invested in DS and what appears to not be much of a stretch in achievement to Poser 13.  

Is there a content list someplace?  

It would surely be cool for some new content too, but from what I've read this is an early release and there are still pieces that are not complete.
