About a possible "next" Poser version?
There is no news out yet, so let's wait till Nerd3D has settled in and give him and the team some time to focus on the main improvements they gather all over the end user base.
Game Dev is still pretty new, and SR5.2 (for all versions of Poser10 to PP2014GD) is very stable.
Fingers crossed.

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