Pauline and Paul are now developer meshes as well, if I am not mistaken. People with Poser Pro 11 can use the tools to make lots of variations for them, as well as to fit clothing and so on. I think in the end, a lot of DIY-capable folk will be making their own content. However, there is a large segment of Poser users who do not yet know what to do with modelling and modification utilities, and they will be the ones who may need add-ons. Well-created add-ons (clothing, characters, poses) will always be welcome and appreciated even by folks who can make their own content for Pauline (and Paul). There'll be some support for good quality products.
