I just uploaded a picture to my gallery that pretty much sums up what I enjoy most doing in Poser:

Creating my own sculpts, preferrably using old and obsolete figures.

It also exemplifies the level of realism I'm happy with.

Poser 11 allows me full control over the look and the way my sculpts move.

Firefly allows me great flexibility in how my renders look.

I don't like the way Superfly looks, and I don't like how slow it is.

(To those who say it is faster than Firefly, that's because many Firefly products use unecessary complicated shaders that bog Poser down. If you know how to optimize Firefly, it gets lightning fast. The Firefly renderer also allows a much nicer looking preview, if you know how to build your shaders right)

And if I wanted to truly achive photorealism, I wouldn't use Poser anyway.

So, for the foreseeable future, I'll very likely stay with Poser 11, having installed PP 2014 still as a backup plan, should something happen to the Poser 11 license server.

I might try out Poser 13, but unless:

a. I get a new laptop with a GTR card to make Superfly fast enough to compete with my optimized Firefly...

b. Supefly can do displacement maps so it won't need meshes that were subdivided into a gazillion polygon ...

c. It gets as easy and reliably to use as Firefly with a nice preview...

d. ...or Poser 13 suddenly adds any other MUST HAVE feature it suddenly find I can't live without...

... I doubt I'll upgrade.

I'd happily pay $1000 for a "perfect" Poser that gives me all the features I truly need, but it looks Poser is going into a direction that is not mine anymore. 

New tech is good, but only if it serves an actual purpose.
