The percentage of bitching about 'Poser, versionX' on websites is hardly any kind of indicator as to sales. What there is is a growing nonvocal majority for whom the program does what they expect....or else they simply don't bother with arguing on a forum. I rather suspect that the 'Hell will freeze over before you pry my P4 out of my cold, dead hands' crowd would drop it in a second if some of the enhancements that the userbase has been asking for get implemented....save in the few cases of those afraid of new tech or simply not interested or unable to upgrade. P7P has a few more features to obtain before it gets close to that 'pro' (new, faster lighting engine, rigging enhancements or just adding an out and out weightmapping scheme, multithreading the dynamics, per bone sticky IK, and IMHO, and out and 'animation room' with none of the library pallet nonsense; just a viewport, the dopesheet, a triple graph display, things like that.), and that doesn't even consider the render engine, because to get that more professionally inclined user, its the animation controls that are going to be the attractor. If Poser ever got to the point where you could do quality character animations with comparative ease for use in other apps, it would take off once again... And let us know how the project goes, RD! If what you imagine is doable (particularly if you could work out rigging conversion for the older meshes), it might be the very thing to light a fire under both development teams...particularly if your app could export in Poser native, where it could be used as an animation plugin for something like Vue. If you get to that stage, you might even want to contact the vendors about compatibility issues. Some would ignore you, but some are geeky enough to think an open source app would be coolbeans....
