Quote - i'd rather say:" How many times will the Poser community buy USELESS promises?" as we all know, poser's archaic joint-system bends geometries like sticks. when you bend a stick, it breaks. the announcement promises that now you can render your broken sticks even faster. does that really make you happy?

What are the useless promises?  The last two reasons they gave will greatly benefit anyone currently using Poser.  Of course, they won't be doing anything new, just doing it faster and with less hassle.  I gather that's your point; that broken figures will still be broken and wonky deforms will still be wonky.  AFAIK, that's all true.  Still, there are figures that do work really well in Poser, and now we'll be able to render them quicker, which many of us will be happy with.

I'm hoping that there will be improvements made to the bending and deforms, but I don't see the concern some people have with this.  I don't see why traditional figures couldn't coexist with an improved figure type, nor why it would need to be difficult to convert the current figures to a new type of rigging should one become available.  I don't think the problem is the skeletons, but rather just the weighting of the joints is imprecise compared to what could be achieved with weight mapping.  If a new system could be devised in which traditional joint parameters could be converted to weightmaps and improved further, then I think that'd be very good.  I don't really have a problem with having to weld seams or not having more than 2 pieces meeting in the same place.  I was looking at soft body simulations in blender and noticed that the softness can be controlled by the weight map (makes sense IMHO).  I hope we get that someday, but I wouldn't go so far as to say that a version 7 that doesn't include this is "USELESS". 

I use Firefly for more than just rendering figures, so my opinion may seem unusually biased.
