BodyShop appears to be something that stays around because it was part of the first game release, and no one wants to hear complaints that it was "taken away". But the lack of investment in development in almost five years should be sufficient statement to reveal the prospects of them ever improving it.
Well, they'd have had a regular riot on their hands if they *had* taken it away, since they haven't provided any other tools for creating clothing, genetics or accessories. I'm sure if they had just stopped supporting it, somebody would have come up with a viable alternative (not sure whether it's possible to actually make new BodyShop content from scratch using SimPE alone?), but it would have caused a tremendous uproar in the meantime.
