I showed Jenn the thread here and told her people were wondering if they bought all versions of Poser and were they going to develop it. Here's what she replied back:
We purchased ALL versions of Poser. We are the only owners of any Poser Software going forward.
We are only going to broker Poser Pro 11 only and price that at the low price of Poser 11 so that EVERYONE can have full access to Poser 11 and Poser 11 Pro. So everyone can use the same great piece of software.
I think that was a very smart move . One version to support and develop rather than multiple.
