Recreating the same items, but for new figures, is not making new content, it is recycling old content but hoping to profit from them. Many artists realize this, which is why new figures don't succeed. If you are offering a new figure, but there really isn't all that noticeable an improvement, but you want me to rebuy all the money I've already spent, that won't happen :p Now, if a vendor creates something I find interesting, I purchase it, as my item history suggests, seeing as I've bought over 300 items at renderosity alone. If daz or whoever thinks I want to rebuy all those items though because they've added a few small features, they are crazy, and I think a lot of artists are like myself.

Regardless of what you consider new content... the bottom line is: if you don't invest in the new figure, it fails.
