Don't go getting your hopes up, but Bluefin Tamashii Nations USA recently posted the following on their Facebook: "The reception for Sailor Moon gives us great confidence for females from other series. More girls? MOAR GIRLS! Power up for tomorrow night and the Nex (sic) 3 weeks!"
Do note the part about females "from other series." Whether this means they might be more receptive to females in current series, such as Mega Man/Rockman and Power Rangers/Super Sentai, or just mean bringing on new series with a female focus, we can't be entirely sure. Nonetheless, action figures of female characters have a reputation for being a difficult sell in the west, so hopefully this bodes well for future prospects such as the recently-teased Iris.
