I too am disappointed there isn't a reasonably priced upgrade path from Poser Pro 11.

I do a lot of animation so was interested in upgrading to P12 but the P12 Queue  Manager constantly fails because it can't find some bom file.  So I hoped P13 would give me the faster render times that P12 did while providing a functional Queue Manager.

Unfortunately it appears I cannot test the P13 Queue Manager functionality because it asks for a license number when I send a movie render to the Queue Manager.

I would be far more impressed with P13 and likely to buy it if--

(1) I could verify through the trial version that Queue Manager worked 

(2) I could run my huge collection of P11-compatible Python scripts in P13 (or there was a clear, available methodology for updating the scripts)

(3) there was a reasonably priced upgrade path from P11 Pro
