Comparing Poser in any incarnation and Cararra is apples and kumquats; one is a figure manipulating, animating and rendering app, the other is a modelling program with plug-in support for dynamics. 

Carrara (even v5) is much much more then you say it is, are sure you don't mix it up with Hexagon? Carrara 5 can do a lot of things Poser can do and Carrara 6 will be very close if not beyond Poser. Carrara has excellent rendering engine. Handles animation very well. Rigging characters no problem. C6 will have dynamic cloth & hair and so on and animation features that go beyond what poser can do, let's not even mention the improvements in the rendering engine as well as being able to create landscapes and all that comes with that.

*They make their money on =content=.....and the king of content use is still Poser.
*I wouldn't even be too sure about that either...... D/S 1.7 has over 38,000 downloads after it's release 2 weeks or so ago. I seriously doubt Poser 7 has sold so many copies, Poser 6 may not even had such sales. I do realize not all of those people are serious users, but that goes the same for poser. 

*So we'll see what P7Pro is made of.....it might just bury DS, you know....
*Considering that P7Pro will not be cheap and some of the pro-features are free to D/S users, I doubt that. We all know that a lot of poser users haven't even upgraded to P7 yet (and may never do so), it's very likely that even less will upgrade to P7Pro. Also if D/S keeps on going as it does (and seeing that even some of the die-hard poser users are promoting it a lot now), it soon will be equal to Poser 7 and Poser 7 Pro, if not beyond it. You also need to keep in consideration that a stable Poser version takes a long time with EF..... P7 for sure isn't stable and it took them ages to get P6 stable. DAZ is releasing new versions a lot quicker, I think EF is betting on too many cards these days, they don't seem to be able to keep up with everything.
