Since its introduction last August, Forces of Destiny has had a mixed reception. On one hand, it's a toy line for parents to buy their daughters. On the other hand, so are all the other ones. Is a lightsaber or a figure better because the packaging is different? Sometimes it is - marketing accounts for a disturbing amount of your toy preferences. Be it a comic, a cartoon, a commercial, or some other brililant insight your tastes were funneled to the stuff you like somehow - and this happens to this very day.
The doll line was not spoken of at all during Hasbro's collector event, but a few items were on display. Nothing you haven't seen, and the future for this line is a bit of a mystery. With no new products, you can only make assumptions.
