Well it depends, I guess, on your current workflows and what version you're upgrading from (I see you mention 2014) and what you would like to see improved from your current version. Think of the issues in your current workflow, do any of the new features move to fix that issue, that justify the price tag for you. Are you interested in an inline PBR renderer?

It kinda goes against my grain to attempt to sell you Poser 11 in the Daz Studio Forums but here goes ;D

Here are some of the main things that are getting Poserphiles excited about Poser 11.

Superfly the much touted PBR Cycles renderer of Blender fame is now in built into Poser. This won't offer much for people who already have a prefered 3rd party renderer such as Reality or Octane but may knock the socks off those Firefly purists out there looking for some increased realism. The integrated Material presets that hold settings for both render engine are a nice touch and keep things clean. To be honest I have been less than impressed with some of the promo material for Superfly, flat jade dragons and fake gold look king tut heads. But it's early days yet and have seen some mind blowing stuff done through Blender in the past. The downside is also if you don't have an Nvidia GPU you may see longer render times.

The OpenGL Realtime toon preview and render with Geometric edge seems to have good possibilities for Toon render fans.

Finally moving the library away from Adobe Flash to what I believe is now Javascript based. The quote was "people in California have moved away from building with Adobe bricks"

Adaptive rigging looks interesting but I haven't seen a convincing use of this either as yet.

HD morphing through the morph brush on SubD figure. Again haven't seen this used. But it sounds good in theory.

All up if you want my actual honest personal opinion, I won't be purchasing it, as I really don't see the value for the price tag anymore in consideration of what the direct competition is offering. Plus Kai Krause was an insane genius with UI design, sometimes I can't decide if the Poser UI is genius or just insane.

Really you need to spend a little time assessing the new features and how they may benefit your own workflow or not. And make a decision based from there. I would tend to hold off for a bit even if you're tempted to give time for any bugs that were rushed out the door to come to light and for people to have time to show what the new features can do also which may sway your final decision. Poser is a tool and it's use is the most important aspect of it's suitability to task. There is no point me recommending you a reflex hammer for demolishing concrete slabs.

Did that sound unbiased enough for you? ;) I hope it may of been of some help, now I need to go take a long scalding shower.
