I think I'm sold on P7, once I have the money.  I think I'm most interested in the new cr2-driven animation potential - but I can't remember what it's called!  Ockham was experimenting with it in a thread a few months back, I think.  I'd like to try that, to see what can be done with it.  And it sounds like there are many other benefits, too.

I'm kind of leaning toward V3, primarily because the V2 to V3 version could be used with my current clothing items with little difficulty.  The big problem will be porting character morphs and creating new textures.  Unfortunately, TDMT never quite reached the point where it permits easy transfer of character morphs.  :(

Another related question: what about add-ons?  Wardrobe Wizard, that Face-shop thingie, what is recommended?

Cage can be an opinionated jerk who posts without thinking.  He apologizes for this.  He's honestly not trying to be a turkeyhead.

Cage had some freebies, compatible with Poser 11 and below.  His Python scripts were saved at archive.org, along with the rest of the Morphography site, where they were hosted.
