Indeed, and Poser8 is from 2 years ago and DS4-Genesis is from mid this year. Looking fast??? Yes it is still 2011 :-)

Poser9-PP2012 also have new techology; unfortunately, the 2 apps are not completely comatible any more.
Older content works in both, but the newer content is single application.
Miki3 not fully operational in DS4 and Genesis not fully operational in Poser.

If you are in the middle of a project? I would perhaps upgrade, yes, but stick to the line I have.

Poser 1, 2, 3, 4, 5, 7, P8 and PPro2010, P9 and PP2012, P10 and PP2014 Game Dev
