Well, they've always segregated the line, just not so visually... Now CW stands out as not only completely kid-targeted but completely different looking to the realistic line too, at least to us of course. Soon it'll be packaged completely different too.
Hasbro wants your money too, I'm sure, but to them your (collector) money isn't enough to warrant the tooling for Satine, who they figure the minimums needed to make whatever profit margin they insist on meeting isn't there... I'm sure you're not alone too, others want her. To me it's like Padme figures, which I think they consider equally sketchy for the realistic line, and so unless the balance is there, we rarely get the odd Padme in ______ (insert gown type there).
Satine, in a line aimed at the kids 99%, is just a matter of risk vs. reward, and she loses out to basically everyone else in the pool of characters they can make.
I'm honestly surprised they even came out and have said, "No", with nothing else about it really... I figured figures like that they'll keep "No" close to their vest and just say, "Maybe if we think she can be slotted in and sell", and just keep collectors in the dark on their actual opinion, to avoid backlash.
