That's all well and good, lmckenzie, and I agree with you for the most part.
The thing is, Poser will have to be developed further. All software companies need to release new versions, or else the public gets restless, or other apps fill the void. D|S for one, Quidam for another, are willing to fill that void.
So what kind of improvements can future versions of Poser implement if not something more advanced and better? You know, just working with what they currently have isn't going to cut it.
And even if they put all their effort into CP and forget about updating Poser entirely, CP is only a retail outlet for Poser content. I can't see it as being any kind of intelligent business move to let the app stagnate while working on better content, just as I can't see it as good to only make minimal advances to the program itself.
Where else is there to go but up? Well, "down" or "nowhere" would be alternatives, but would only result in Poser losing everything it's gained as a program.
