But what I find more problematic is the state of their website:
Here you can read that this software is "now in its fourth major iteration", while "version 5" seems to imply that it's in its fifth "major iteration" (or am I missing something, once again?).

Well it was definitively more popular before about five or seven years - it was my 'second option' when I brought XSI 4 Foundation to my home. And in this time, I was able to get a job with pMessiah in place where I live - to be honest, nobody wanted XSI skills.
But this telling a much more about current state of character animation. 3d seems to grow up in every direction except this one. From about 100 users of 3d apps, probably three or five are able to setup a simple IK chain, and those three or five were able to that for a long time. The same, or even worse ratio, applies to zBrush people, especially those 'born in zBrush'.
IMHO, Softimage makes a great move, running into the field of simulation and 'general' VFX.
That I know, one of pMessiah developers is a si-community member Thomas Helzle.
