only thing I know about is Hasbro's new Disney Princess line.
disney star darlings and shopkins shoppies dolls other then that i don't think these's any new lines.
Star Darlings and DC Super Hero Girls are two I've heard of recently (there's also a really cool Barbie collector Wonder Woman coming out soon). Hasbro is getting the license for Disney Princess, that's probably why EAH is getting skewed younger.
Hopefully they're bringing out some more Bratz and Project MC2 in 2016 too.
I'm looking forward to seeing what Hasbro does with the Disney Princesses. The Descendants line looks great, so it gives me hope for what they'll do with the princesses.
