I frequently bow down to the finding skills of Tumblr's Darth Alinart. I just spotted three new posts with all new items, so here's what was found for DCSG:

I'm glad that the action figure side of this line is getting a lot of stuff. It's good to see action figures in the "girl" toy aisles. I like the sound of the bedroom ones and the Batgirl vehicle set looks pretty cool. I probably won't get any, although if they put Harley and Wondy in the PJs from the webisodes, I'm in.

I'm disappointed in the dolls though, because there are no new characters. I'm not sure what's going on with the listings, because all three are clearly for a doll in a transforming outfit, but the photos on Starfire's show the basic Starfire doll. I'd love to see her with a new doll so quickly though.

Then Supergirl has a locker playset, but really, WHERE ARE THE OTHER NEW CHARACTERS?

They're going to bore people if they don't make more characters faster than this. Although these listings mention Fall 2017 so maybe we'll get other new characters a little bit earlier than that?

Wondy, Bumblebee, Harley and Ivy are all getting Funko Rock Candy figures "this winter."

I really love Harley's, but Bee might just be the cutest. It's also nice to see Ivy, with her being left out of certain other lines like the plush and vinyls.
