there may be only one public version prior to the boxed set, but if many users complain of crashes and problems during the first week after download commences, they may put out a patch, which may delay release of the boxed set. my main interest in C6Pro is that it may allow users with poser content to dispense with poser entirely, but that remains to be seen. for all we know, e-f may produce P8Pro in such a way that the rendering engine isn't vintage 90s algorithms.
